What should I do if the infrared thermometer is suddenly exposed to an ambient temperature difference of 20°C or higher?
Disadvantages of infrared thermometers
(1) The emissivity of the object being measured must be accurately determined;
(2) Avoid the influence of high-temperature objects in the surrounding environment;
(3) For transparent materials, the ambient temperature should be lower than the temperature of the object being measured;
(4) The thermometer should be aligned vertically with the surface of the object being measured. Under any circumstances, the angle should not exceed 30°C.
(5) It cannot be applied to temperature measurement on bright or polished metal surfaces, and temperature measurement cannot be carried out through glass;
(6) Correctly select the tracking coefficient, and the target diameter must fill the field of view;
(7) If the infrared thermometer is suddenly exposed to an ambient temperature difference of 20°C or higher, the measurement data will be inaccurate. The measured temperature value will be taken after the temperature is balanced. .
Characteristics of infrared thermometer
1. Non-contact measurement: It does not need to come into contact with the interior or surface of the temperature field being measured. Therefore, it will not interfere with the state of the temperature field being measured, and the thermometer itself will not be damaged by the temperature field.
2. Wide measurement range: Because it is a non-contact temperature measurement, the thermometer is not in a higher or lower temperature field, but works at normal temperature or conditions allowed by the thermometer. Under normal circumstances, it can measure negative tens of degrees to more than 3,000 degrees.
3. Fast temperature measurement: fast response time. As long as it receives the infrared radiation of the target, the temperature can be fixed in a short time.
4. High accuracy: Infrared temperature measurement will not destroy the temperature distribution of the object itself like contact temperature measurement, so the measurement accuracy is high.
5. High sensitivity: As long as there is a slight change in the temperature of the object, the radiation energy will change greatly, which is easy to measure. Temperature measurement of small temperature fields can be performed.
6. Temperature distribution measurement, and temperature measurement of moving or rotating objects. Safe to use and long service life.
