thermometric indicator (thermometers) is a thermometers that uses infrared to transmit numbers to sense the surface temperature of an object. It is convenient to operate, especially for measuring high-temperature objects. Widely used, such as steel casting, furnace temperature, machine parts, glass and room temperature, body temperature and other objects surface temperature measurement. Infrared thermometers are used more frequently.
