Reasons and solutions for high temperature of infrared thermometer
Reasons for the high temperature of the infrared thermometer
1. The temperature of the measured object was not correctly estimated.
2. The target emissivity is much higher than the expected setting or the emissivity adjustment is incorrect.
3. The spot size of the measured target is too small.
4. There is reflection interference from the background heat source.
5. Wrong type selection, failure to correctly analyze the measurement band applicable to the measured target.
6. Lead wire electrical noise caused by strong magnetic field or incorrect selection of interconnection cables or cables and wire problems of AC power lines.
7. The lens or window of the thermometer is cloudy.
8. The cable is not properly grounded, resulting in no shielding.
The solution to the high temperature of the infrared thermometer
When the first problem is caused, we can choose other thermometers to compare the temperature measurement. If it is caused by the second problem, then we can reset the emissivity value. If it is caused by the third problem, we need to adjust the temperature measurement distance. If The solution caused by problem four is shading treatment to shield the background heat source. If it is caused by problem five, you need to re-select the model. If it is caused by problem six, you need to do electromagnetic interference protection. If it is problem seven, the solution is to replace Lens or window, if it is caused by problem eight, it can be solved by rewiring.
