1,Overview

CWH800(A) Mine Intrinsically Safe Infrared Thermometer - This product is used for measuring the surface temperature of equipment in coal mines. It is a professional handheld non-contact infrared thermometer with a solid design, easy to use, high measurement accuracy, and a wide temperature measurement range. It is used for measurement and maintenance in coal mines. This handheld non-contact infrared thermometer can be used to measure the surface temperature of objects that are not suitable for traditional contact measurement methods (such as moving objects, electrified surfaces, and difficult-to-reach objects, etc.).
