Description

Netsushin in collaboration with the National Institute of Advanced Industrial Science and Technology (AIST) has developed a new type of High Temperature platinum Resistance Thermometer (HTPRT), model HTS-21-1000.  

10mK Stability at 1000ºC

According to ITS-90 (International Temperature Scale 1990), the maximum temperature for PRT has been defined at 961.78ºC, the freezing point of Silver (Ag). Netsushin has developed new PRT (HTS-21-1000) for high temperature and realized extremely better stability of ±0.01ºC (10mK) at 1000ºC.  

Features

  • Wide temperature range, 0 to 1000ºC
  • 0.01ºC (10mK) stability at 1000ºC
  • Available to place HTS-21-1000 not only vertically but horizontally
  • Better accuracy with few calibration point.
  • The longer use at high temperature, the fewer drift rate.
