Causes and Solutions for High Temperature Infrared Thermometers
Temperature measurement method of infrared thermometer
1. When using an infrared thermometer to measure the surface temperature of luminous objects, such as aluminum and stainless steel, the reflection on the surface will affect the reading of the infrared thermometer.
2. Before reading the temperature, you can place a tape on the metal surface. After the temperature is balanced, measure the temperature in the tape area.
3. The infrared thermometer can be used to move 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 equilibrium.
4. It is best to place the thermometer in a frequently used place.
Reasons why the temperature of the infrared thermometer is too high
1. Failure to correctly estimate the temperature of the object being measured.
2. The target emissivity is much higher than the expected setting or the emissivity is incorrectly adjusted.
3. The spot size of the measured target is too small.
4. There is reflection interference from background heat sources.
5. Wrong selection and failure to correctly analyze the measurement band applicable to the measured target.
6. Electrical noise in the leads caused by strong magnetic fields or incorrect selection of interconnecting cables or cables and wire problems with AC power cords.
7. The lens or window of the thermometer is cloudy.
8. The cable is not shielded due to incorrect grounding.
How to deal with high temperature of infrared thermometer
When problem one is caused, we can choose other thermometer equipment to compare the temperature measurement. If it is caused by problem two, then the emissivity value can be reset. If it is caused by problem three, we need to adjust the temperature measurement distance. If The solution caused by problem four is shading to shield the influence of background heat sources. If it is caused by problem five, it needs to be reselected. If it is caused by problem six, electromagnetic interference protection needs to be done. If it is caused by problem seven, the solution is to replace it. If the lens or window is caused by problem 8, it can be solved by rewiring it.
