An infrared thermometer allows surface temperature measurement without direct contact, making it suitable for products coming out of curing ovens or surfaces that are difficult to access. However, to ensure reliable results for production quality control, it is important to understand the measurement principle and the factors that affect measurements on painted and coated surfaces.

Around 6 or 7 in the evening, the gym becomes packed; the music drowns out the sound of heavy breathing, and the air conditioning runs at full blast behind closed doors. At first glance, everything seems fine: the room is cool, the lights are bright, and the equipment is state-of-the-art.
