How to choose a pyrometer: top best for home, for production

Pyrometers or temperature detectors are widely used devices designed to measure temperature without direct contact, at a distance. Built-in infrared sensors are able to determine the degree of heating of almost any material, which is why pyrometers (non-contact thermometers) are in demand in various professional fields. The best pyrometer models are characterized by a wide range of additional options, accuracy of the output data and ease of use. Our experts analyzed customer reviews and technical parameters of popular devices and compiled a TOP 10 rating of the most worthy and reliable representatives in their class.

What types of pyrometers are there?

A device designed to quickly determine surface temperature is available in several types. Pyrometers are usually divided according to the principle of operation and aiming, according to their design and measuring capabilities.

Optical

They compare the radiation emanating from a certain object with the light from a filament in their measuring lamp. Thus, a temperature difference is established.

Optical pyrometers compare radiation from an object with a standard

Color

Thermal radiation is measured in a certain spectrum, for example, infrared. They have high accuracy and are often used in everyday life.

Color pyrometers are the most popular, they are easy to use and give accurate readings

With laser sight

The temperature is measured non-contactly in an area clearly defined by a laser point. Mostly medical and household models belong to this type and demonstrate high accuracy.

The laser sight in the pyrometer allows you to measure the temperature at a specific point

Stationary

Such pyrometers are used in production; the devices are quite large in size, equipped with a protective casing and an additional cooling or heating system.

Stationary pyrometers are most often used in production

Mobile

Compact small models are most often used for household purposes and for measuring temperatures in hard-to-reach places. Accuracy depends on quality; good portable devices are as good as stationary ones.

Mobile pyrometers fit in your hand and weigh little

Text-digital

The measurement results of such pyrometers are displayed in degrees. Sometimes additional information may be provided.

Most pyrometers show the measurement results in degrees on the display

Graphic

The device generates an image on the screen showing temperature changes. The models are highly visible.

Some pyrometer models provide information about thermal radiation in graphical form

Tips and tricks when choosing infrared thermometers on Aliexpress

Not all pyrometers measure temperature accurately. The quality of the device is of great importance. At this point you should pay special attention when choosing. If accuracy is required, it is better to avoid cheap models.

Note! Even high-quality infrared thermometers cannot correctly measure temperature on all materials. This must be taken into account when using them. Pyrometers cannot determine the temperature of reflective and wet surfaces (for example, stainless steel and wet leather). This happens due to re-reflection of the beam.

A pyrometer (infrared thermometer) is a device for non-contact temperature measurement.
The temperature range of the device must be selected to suit your tasks. For example, an industrial infrared thermometer with a large range (from -50 to 1600 degrees) is suitable for measuring high-temperature objects. If this is not required, a model with an upper limit of measured temperatures of 380 or 580 degrees is also suitable.

Any medical infrared thermometer is suitable for measuring a person's temperature. However, if its range is high enough (up to 100 degrees, for example), it will have many additional applications, such as determining the temperature of food.

Also, when choosing, you should pay attention to additional functionality. Many industrial thermometers are equipped with lasers, which are used for target designation. Using such devices, you can very accurately select the area to measure the temperature.

Additionally, industrial pyrometers can also detect humidity levels. Instruments for determining it are called hygrometers. Medical models can be equipped with pulse and temperature meters. Such devices are called pulse oximeters.

Using these recommendations, you can purchase a good infrared thermometer for certain tasks. Any of the models presented in the rating is worthy of attention and will be a good choice for your money. A high-quality thermometer will properly measure temperature and perform its other functions and will be able to serve faithfully for many years.

How to choose the right pyrometer

The choice of device depends primarily on where and for what purposes it will be used. Some models are better for measuring body temperature, while others are designed for culinary purposes.

Which pyrometer to choose for your home

The most popular in home use are portable infrared devices. A stationary device operating from the network is unlikely to be useful for domestic purposes, despite its high accuracy. When choosing a pyrometer for your home, you need to consider:

• temperature range, in everyday life there will be a sufficient range from - 50 to 380 ° C;
• accuracy, the error of the device should be no more than 3 degrees;
• range - pyrometers can be contact or non-contact; when using the latter, you need to take into account the optical resolution, or the required distance to the object;
• speed, in everyday life it is convenient to use devices with a response from 0.1 to 0.15 seconds.

Also, when comparing pyrometers and choosing the best one, you can take into account additional parameters. Some models can measure humidity. It is useful if the device is able to save the results of tests performed in the built-in memory.

Which pyrometer is better to choose for a pastry chef?

When choosing a pyrometer for baking in a workshop or at home, you can buy a non-contact device with a range from - 50 to + 400 °C. But models with a thermocouple perform best in cooking; they are connected to the main unit and measurements are taken using the contact method to obtain the most accurate results. Then the test is repeated remotely to compare the indicators; the difference usually reaches several degrees.

In cooking, contact pyrometers with a thermocouple remain the best

How to choose a medical pyrometer

Medical devices are often used instead of conventional thermometers. You need to select a device according to the following parameters:

• contact or non-contact action, devices of the first type are more accurate, although the second can be used for several people without disinfection;
• accuracy, for a medical pyrometer the minimum error is important;
• functionality, it is useful if the device is equipped with a sound signal and can indicate the completion of the measurement.

Important! The medical device does not require a large temperature range.

How to choose a non-contact infrared pyrometer

The best pyrometers for measuring temperature using a non-contact method are very popular in everyday life. Such devices demonstrate high accuracy and are versatile. They can also measure very hot, dangerous or hard-to-reach objects.

When choosing, you need to look at several characteristics:

1. Range. If you only need to determine body temperature and weak thermal radiation from surfaces, you can choose a device with small values. For culinary use, you need to buy a model with a wide range, and it is desirable that even very high temperatures are kept away from the maximum possible readings of the device.
2. Spectral sensitivity. It is better to choose a device that operates on short waves; it is suitable for most household measurements.
3. Chroma. Usually, single-color pyrometers are sufficient for home use. Two-color models should be chosen if you need to evaluate the temperature of very small and hot objects, as well as objects whose radiation is partially blocked by any contamination or obstacles.

When choosing a home pyrometer, first of all, you need to evaluate its thermal range.
Infrared devices equipped with a laser sight are considered the best. They help measure the temperature of an object at a specific selected point and thus reduce the likely error.

How to choose a pyrometer for measuring temperature

If the device is to be used instead of a thermometer, first of all you need to decide on its type - contact or non-contact. Devices from the last category are recommended for young children. But for adults and teenagers it is better to use contact pyrometers - frontal or ear. They give more accurate readings and are almost as good as mercury thermometers.

How to choose the right thermodetector

When choosing a pyrometer that meets your expectations, you must consider the following criteria:

1. Temperature Range. An inexpensive infrared pyrometer with a range from – 50 to + 500 degrees is suitable for home use. This is enough to determine the temperature of the car engine, the degree of heating of water, oven, meat, and cooking utensils. In industrial settings, when measuring the heating of metals, production equipment, etc., a device with greater capabilities may be required, but such devices are more expensive.
2. Optical resolution. The indicator determines at what distance measurements can be taken. Devices with a resolution of up to 10:1 will measure temperature at a distance of up to 1 m, a reading of up to 30:1 accurately reflects heating at a distance of up to 3 m. Models with a resolution of more than 50:1 and higher can measure temperature at a greater distance.
3. When you need to take many measurements, you need a pyrometer that can store readings. Models with photo and video recording of measurements are also great.
4. Response time. If you need to measure surfaces whose temperature changes quickly, you need a device with a minimum response time. For example, when working with electrical wiring, 1s is not enough; it is better to choose a fast thermal detector that can scan in 0.5s. Expensive professional modifications have the lowest rate - about 0.15 s.
5. Determination of humidity level. The function is found in professional devices and allows you to measure air humidity. This option is necessary to monitor the indoor climate, determine the likelihood of condensation and mold formation.

There is another important indicator - the emission factor. For household models it is 0.95; such devices are suitable for measuring materials with a matte finish - rubber, plastic, concrete or brick. Glossy surfaces have a lower coefficient; to work with such materials you need a model with an adjustable indicator.

A type K thermocouple (additional option) allows for contact measurements, and a double laser beam allows for more accurate determination of measurement locations.

Which pyrometer is better - laser or infrared?

Pyrometers come in optical and infrared types. It is the latter that are usually used in everyday life; they are compact, have good accuracy and display the results in digital form.

As for laser devices, they are a type of infrared. We are talking about devices equipped with an aiming system. They are more convenient to use than devices that do not have a laser sight. The simplest models of pyrometers measure temperature “over an area” and do not focus on a specific point on an object. Laser-based devices evaluate infrared radiation over a selected small area and therefore exhibit increased accuracy.

Pyrometers with a laser sight are objectively better; they guarantee high measurement accuracy

Technical characteristics of non-contact meters

The infrared pyrometer is designed for non-contact temperature measurements and is used in enterprises to control the production process. The principle of operation is based on measuring the energetic brightness of part of the infrared radiation of a thermal object that has passed through the optical system and absorbed by its receiver, and converting the measured brightness into a digital signal proportional to the temperature of the object. Temperature values ​​are displayed on a liquid crystal display in digital form, on a PC and an analog signal (0)4-20mA. Effective wavelengths range from 0.656 microns to 14 microns.

The industrial pyrometer consists of a measuring unit, a switching unit and a set of connecting cables. The measuring unit includes a lens, a sighting device, and an information processing and display unit.

What to look for when buying a pyrometer

Choosing a device that will have the best price-quality ratio and cope with all the tasks is easier if you know what to look for when purchasing.

Main types of devices

All pyrometers work by analyzing infrared radiation emanating from the object of study. But depending on the design features, the method of reading or issuing information, devices come in several types:

1. Devices with a laser sight determine the temperature not of a wide spot of the surface, but of a specific point. The measurement itself occurs in the same way as with other devices; the laser here simply works as a mark. Most medical and household pyrometers have such a sight.
2. Stationary devices are used in industry and production. They have good characteristics, but are large in size.
3. Mobile devices are those that can be purchased at hardware stores or hardware stores. They are compact and lightweight, designed for a wide range of tasks and can have the same characteristics as stationary devices.

Depending on the way information is displayed to the user, pyrometers can be text-digital or graphic. The first display specific data: the measured temperature and service information are written in numbers. Graphic pyrometers are used when it is important to obtain not data on a specific point or area, but an overall picture, as on a thermal imager.

Characteristics of pyrometers

The optical resolution of a pyrometer is its key characteristic, which determines the accuracy of measurements at a certain distance, and, ultimately, the cost of the device. This is the ratio of the optimal distance to the measurement object and the diameter of the measurement spot. The larger it is, the more expensive the equipment costs. More advanced models have the ability to take point measurements inside the spot.

The emission coefficient is an internal correction of the device for the quality of the surface whose temperature it will measure. Most household pyrometers have an emission factor of 0.95. Such a device “sees” objects made of matte materials well: plastic, painted metal, brick, as well as the human body. If you need a device that can determine the temperature of different media and materials, it is better to choose a pyrometer with an adjustable emission coefficient.

The range of measured temperatures is on average from -50 to 500 degrees. This is enough for household and construction needs, as well as in medicine and cooking. Many pyrometers work with exactly these values. The lower limit rarely decreases, but the upper limit can reach 2200 degrees. And this is already specialized, expensive measuring equipment.

Response time is the speed at which the device operates. For static measurements this characteristic is not important. But for those who need to measure temperature dynamically or repeatedly, it is important to have a minimum response time. Accordingly, the faster the device operates, the more expensive it is. On average, this value is in the range of 0.5-1 seconds; professional equipment has a response time of up to 0.15 seconds.
