Overview
Standard photoelectric pyrometer
Product Details
The combination of high-precision photoelectric pyrometer standard blackbody radiation source and reference thermometer constitutes the metrological standard. The LP4/LP5 series high-precision photoelectric pyrometer is a series of stable performance photoelectric pyrometers developed and produced by German company KE, which can be used as standards. Its main function is to serve as a standard for radiation thermometers during high-temperature testing. This device can be used in conjunction with a blackbody radiation source at (220~3000) ℃; Verify and calibrate the radiation thermometer within the scope. It mainly uses a blackbody radiation source to provide stable radiation temperature in the laboratory, places high-precision photoelectric pyrometer and the tested radiation thermometer within the radiation temperature field range, and combines temperature measurement secondary instruments to detect and calibrate the radiation thermometer to obtain accurate brightness temperature.
GermanyKEThe company was founded1975Year, it is the University of StuttgartIKEA derivative company of the Institute of Nuclear Energy and Energy Systems.IKEResearch Institute andKEThe company has a long history of research and development, as well as production of standard photoelectric pyrometers and heat pipe blackbodies. Among them,LPThe series of linear photoelectric pyrometers have been applied in metrology institutes and research institutions in dozens of countries around the world. They have stable performance and high linearity, and can be used as standards in conjunction with blackbody radiation sources500K～3500KCarry out calibration and verification work on radiation thermometers within the scope. Of course, it can also be used separately as a standard photoelectric pyrometer with fast response, high linearity, and high accuracy.
