When Troubleshooting problems in different types of equipment (furnaces, steam boilers, compressors, refrigeration units, freezers, etc.), an important criterion is the temperature. If testing the temperature of the controlled object differs sharply from the normal operation mode (it is too high or too low), it is a warning. Possible emergency.
The temperature of objects (objects) can be measured in two ways: contact and contactless.
the
On the Russian market of measuring devices a wide range of devices. Therefore, the choice of thermometer should be based on the planned dimensions.
Stationary pyrometers are highly accurate and designed for continuous operation. They are functionally rich, high reliability, ease of reporting results, however, have complicated management and for measuring the temperature of objects located in inaccessible (hazardous) areas, they’re useless. Contact devices require setup, calibration, and verification with the help of special techniques. Such a device will not always be at hand.
Here come to the aid of a simple portable contactless devices of the series “ThermaLine”, providing instant measurement. Contact with moving objects or objects with hot surfaces is missing. This inexpensive instrument (much cheaper than stationary devices) is the best option to detect even small rises in temperature. This will prevent the development of defects in serious trouble.

The choice of thermometer also depends on its technical characteristics.
The first major parameter – range plan for control of temperatures. If you only need an energy audit walling (approx) indoor or perform measurements in environmental conditions (on the street), temperature range you can select -50°C …+50°C. To control the temperature in industrial facilities suitable devices that can operate at temperatures exceeding several times the above values. The higher temperature range of the pyrometer, the higher the cost of the device. The most versatile thermometers for a wide range of tasks is a model of BALTECH TL-0215C.
The second parameter resolution temperature. The accuracy of the device depends on this value. It characterizes the smallest temperature difference that is perceived by a thermometer.
The third parameter is the index of sight. It is the ratio of the diameter (S) spots on the object and the distance (D) to object: D:S. For accurate temperature measurements, the size of the object must exceed the size of the spot, otherwise you will measure the average value of the temperature with high accuracy.
The fourth important parameter is the operating temperature range. It shows the temperature conditions for the normal functioning of the pyrometer in ambient conditions.
