12 best pyrometers

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

Increasingly, in production and in everyday life, you can find such an unusual measuring device as a pyrometer. It allows you to determine the temperature of the surface without touching it. This is very important when working with hot objects, as well as in case of difficult access to the object. Non-contact thermometers are in demand in construction, metallurgy, oil refining, utilities, etc. The principle of operation is based on the thermal radiation of objects, which is captured and processed by the device. To choose the right pyrometer for the job, several expert recommendations should be considered.

How to choose a pyrometer

1. Classification. The detection mechanism for pyrometers is different. There are optical, brightness, spectral and radiation devices. The most popular are infrared models.
2. Appointment. Both stationary pyrometers and portable ones are on sale. In some branches of production, it is more profitable to use devices installed stationary in a certain place and operating from a 220 V network. They are distinguished by high accuracy and reliability. It is more convenient to carry out periodic temperature measurements at different points of the enterprise or construction site using a mobile pyrometer. Less accuracy is compensated by its compactness and lightness.
3. Temperature Range. Devices with a certain temperature range are selected depending on the production need. Universal models are capable of determining both negative (up to -50 ° C) and positive (up to 2000 ° C) temperatures. Employees of metallurgical enterprises are better off focusing on a narrower range (+50 … + 2000 ° С), and utility workers will be interested in another limit (-50 … + 50 ° С).
4. Range of action. It is not always safe to take readings near the test object. Therefore, it is important to know from what distance the pyrometer will determine the temperature. Optical resolution becomes one of the main parameters. It shows the ratio of the distance to the object to its dimensions (diameter, width, length). They are capable of measuring the temperature of a model with a sighting ratio from 1: 1 to 20: 1. Long focus ranges from 30: 1 to 100: 1.
5. Accuracy. Each pyrometer has a measurement error that can range from 0.5 ° C to several percent. The best option is an accuracy of 1-3 ° C.
6. Measurement speed. In some places, a person cannot stay for a long time. Therefore, the device must very quickly determine the temperature. For domestic purposes, a device with a response speed of 0.25-0.5 s is suitable. For more high-speed devices, this indicator is in the range of 0.1-0.15 s.
7. Additional options. The cost of the pyrometer depends not only on the basic parameters, but also on the availability of additional options. Some models can determine humidity, while others are able to record the results on a video camera. Functions such as a laser pointer, display backlighting, storage of results in memory will also be useful.

We have selected 12 of the best pyrometers for our review. All of them received approval from the expert community and Russian users.
