  • Introduction
  • Specifications
WFT-202-type radiation pyrometer is a simple non-contact radiation thermometer to measure object surface temperature according to thermal radiation effects principles. It is used to continuous measure temperature of Furnaces, high temperature kiln, salt bath etc. in metallurgy, machinery, silicate and chemical industry and other place can not equip with thermocouple. It usually equip with display instrument to indicate, record and auto-regulating temperature.
It is fixed installation and the temperature sensing device works in 10~80℃. If the temperature above 80℃ or media contain vapor or gas, user can use cooling water or ventilation to decrease temperature and blow the gas to reduce measurement error.
