  • Introduction
  • Specifications
WDL-31 photoelectricity thermometer is a non-contact infrared thermometer. It uses comparing balance method to measure energy of radiation and temperature. It is suitable to measure the surface temperature of stationary or movement objects such as metallurgy, machinery industry in the molten iron, hot forming process, heat treatment, glass industry, textile industry, fabric heat setting, the rubber industry rotation, roller surfaces, semiconductor materials, single crystal, polycrystalline access system etc. it output unify signal and connect with various of recorder, regulator or computer to do auto-control or auto-regulation.
