Causes and remedies for an infrared thermometer's excessive temperature
Infrared thermometer temperature measurement method
1. When using an infrared thermometer to measure the surface temperature of a luminous object, such as aluminum and stainless steel, the reflection of the surface will affect the reading of the infrared thermometer.
2. Before reading the temperature, put a rubber strip on the metal surface. After the temperature is balanced, measure the temperature of the rubber strip area.
3. An infrared thermometer can be used to walk back and forth from the kitchen to the refrigerated area and still provide accurate temperature measurement. It must be measured after a period of time in the new environment to achieve temperature balance.
4. It is best to place the thermometer in a frequently used place.
Reasons for the high temperature of the infrared thermometer
1. The temperature of the measured object is 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 improper selection of interconnection cables or cables and wire problems of AC power cord.
7. The lens or window of the thermometer is cloudy.
8. Incorrect grounding of the cable leads to no shielding.
How to deal with 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.
