An infrared thermometer is a measuring instrument that detects the amount of infrared energy radiated from the surface of a material using an infrared sensor and measures the surface temperature of the material based on that energy. The incident infrared energy on a material, as shown in the diagram, can be categorized into three cases: absorption… Continue reading AD-5635 What is Emissivity？

AD-5635 How to set the emissivity
Accurate emissivity must be set in order to accurately measure the temperature of the material surface with a radiation thermometer. For that purpose, it is necessary to obtain the emissivity of the material, and there are three methods. 1. Compare with a contact thermometer (see diagram below) The object to be measured that has been… Continue reading AD-5635 How to set the emissivity
AD-5635 Measuring Temperature of Water and Glass through Infrared Thermometers
Can temperatures be measured through water or glass using an infrared thermometer? Water, being transparent and colorless, might initially seem to have high transmittance and make temperature measurement impossible. However, in reality, water has a high emissivity of 0.98, making it possible to measure surface temperatures using a typical infrared thermometer. Reference： What is Emissivity? ）… Continue reading AD-5635 Measuring Temperature of Water and Glass through Infrared Thermometers
