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 measured object 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 measured object;
(4) The thermometer should be aligned vertically to the surface of the object to be measured, and under no circumstances should the angle exceed 30°C
(5) It cannot be used for temperature measurement on bright or polished metal surfaces, and cannot be used for temperature measurement through glass;
(6) Correctly choose the follow-up coefficient, 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, and the measured temperature value will be taken after the temperature is balanced. .
Features of Infrared Thermometer
1. Non-contact measurement: It does not need to touch the inside or surface of the measured temperature field, so it will not interfere with the state of the measured temperature field, 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 a normal temperature or under the conditions allowed by the thermometer. Under normal circumstances, it can measure minus tens of degrees to more than three thousand degrees.
3. The temperature measurement speed is fast: that is, the response time is fast. As long as the infrared radiation of the target is received, 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 small change in the temperature of the object, the radiation energy will change greatly, which is easy to detect. The temperature measurement of the tiny temperature field can be carried out.
6. Temperature distribution measurement, and temperature measurement of moving or rotating objects. Safe and long service life.
