WDL-31 series optical pyrometerDetailed product description：

A photoelectric thermometer is a non-contact infrared temperature measuring instrument that uses the equilibrium comparison method to measure the radiated energy of an object to determine the temperature value. Suitable for rapid measurement of surface temperature of stationary or moving objects in industrial production processes, such as melting iron, hot forming processing, heat treatment, glass products industry in metallurgy and machinery industry, fabric heat setting in textile industry, rotation, drum surface, semiconductor material single crystal, polycrystalline bonding, etc. in rubber industry. Output a unified linear signal, which can be used in conjunction with various recorders, regulators, and electronic computers for automatic recording, regulation, and control.
