Standard platinum resistance thermometer R800 series

The R800 series is a standard platinum resistance thermometer development based on the 1990 International Temperature scale (ITS-90) under the guidance of the National Institute of Metrology, Agency of Industrial Science and Technology.
The R800-3T has significantly improved stability and repeatability by improving the temperature sensor structure from the previous model R800-3L.

For traceable temperature and humidity measurement and maintaining sensor accuracy

Covers everything from the vapor pressure point of helium to the freezing point of silver
Up to four constituent can be measured simultaneously
A wide range of models available, including low temperature and high temperature models
Fixed-point calibration and precision comparison calibration also available
stability of silver point (962℃) measurement has been verified by the National Institute development Industrial Science and Technology.
