12 best pyrometers

Increasingly, in production and in everyday life one can come across such an unusual measuring device as a pyrometer. It allows you to determine the surface temperature without contact with it. This is very important when working with red-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 pick up and process the device. To select a suitable pyrometer for work, you should consider several recommendations of experts.

How to choose a pyrometer

1. Classification. The mechanism for determining pyrometers is different. There are optical, brightness, spectral and radiation devices. The most popular models are working in infrared radiation.
2. Purpose. Both stationary pyrometers and portable ones are on sale. In some industries, it is more profitable to use devices installed motionless in a certain place and operating from a 220 V network. They are distinguished by high accuracy and reliability. It is more convenient to conduct periodic temperature measurements at different points of an enterprise or a construction object using a mobile pyrometer. Lower accuracy is compensated by compactness and lightness.
3. Temperature Range. Depending on the production need, devices are selected with a certain temperature interval. Universal models are able to determine both negative (up to -50 ° С) and positive (up to 2000 ° С) temperatures. It is better for workers of metallurgical enterprises to focus on a narrower range (+50 ... +2000 ° C), while communals will be interested in another limit (-50 ... +50 ° C).
4. Range of action. It is not always safe to take readings in the vicinity of the test object. Therefore, it is important to know how far the pyrometer will determine the temperature. One of the main parameters is the optical resolution. It shows the ratio of the distance to the object to its size (diameter, width, length). Short-cut, they are able to measure the temperature of a model with a sighting index from 1: 1 to 20: 1. Long focus is from 30: 1 to 100: 1.
5. Accuracy. Each pyrometer has a measurement error that can vary from 0.5 ° C to several percent. The best option is the accuracy of 1-3 ° C.
6. Measuring speed. In some places a person cannot be long. Therefore, the device must very quickly determine the temperature. For domestic purposes, the device is suitable with a response speed of 0.25-0.5 s. In higher-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 the humidity, others are able to record the results on a video camera. Functions such as a laser pointer, display backlight, and storing the results in memory will also be useful.
