Infrared thermometer temperature high reasons and processing methods
Infrared thermometer temperature measurement method
1, when using infrared thermometer to measure the temperature of the surface of the luminous object, such as aluminum and stainless steel, the reflection of the surface will affect the infrared thermometer readings.
2, before reading the temperature, you can put an adhesive strip on the metal surface, the temperature balance, measure the temperature of the adhesive strip area.
3, with infrared thermometer can be from the kitchen to the refrigerated area back and forth can still provide accurate temperature measurement, it is necessary to be in the new environment after a period of time to achieve temperature equilibrium and then measured.
4, it is best to put the thermometer in the place of frequent use.
Infrared thermometer temperature high reasons
1, did not correctly predict the temperature of the measured object.
2, the target emissivity is much higher than the expected settings or emissivity adjustment is not correct.
3, the measured target spot size is too small.
4, there is a background heat source of reflection interference.
5, the selection of the wrong type, did not correctly analyze the measured target applicable measurement band.
6, caused by a strong magnetic field of the lead wire electrical noise or interconnecting cable or cable incorrectly selected with the AC power line wire problems.
7, pyrometer lens or window turbidity.
8, cable grounding incorrectly resulting in no shielding.
Infrared thermometer temperature high processing methods
When the problem caused by one, we can choose other pyrometer equipment to compare the temperature measurement, if the problem is caused by two, then you can reset the value of the emissivity, if the problem is caused by three, we need to adjust the distance of the temperature measurement, if the problem is caused by the fourth solution is to cover the light processing, shielding the impact of the background heat source, if it is caused by the problem is caused by the fifth, you need to re-select the model, if the problem is caused by the sixth, you need to do Electromagnetic interference protection, if the problem is caused by the seventh solution is to replace the lens or window, if the problem is caused by the eighth can be rewired to solve.
