Chino R800 Series Standard Platinum Resistance Thermometers

The R800 series standard platinum resistance thermometers conforming to the International Temperature Scale, 1990 (ITS-90) have been commercialised under the guidance of the National Research Laboratory of Metrology (Japan).

Features

  • The thermometers cover from vapor point of helium to freezing point of silver
  • Various models are prepared for low temperature and high temperature
  • Designed for use with fixed point calibration cells.
  • R800-0 Standard platinum resistance thermometer for low temperature
  • R800-2 Standard platinum resistance thermometer for medium temperature
  • R800-3 Standard platinum resistance thermometer for high temperature
  • R800-3L Low resistance type standard platinum resistance thermometer for high temperature

 

A suitable resistance thermometry bridge can be found here for utilising the R800 series primary

resistance thermometer.

 

Chino Standard Thermocouples-including Platinum/Palladium and Platinum/Gold types.

 

C810 is designed as a standard thermocouple used for secondary standard calibration at the freezing point of silver and copper. The protecting tube is also easily removable.

C820 is designed as a standard thermocouple for thermometer calibration. Standard electromotive force is ASTM Vol.14.03 E1751. It will also conform to IEC.

C850 is a standard thermocouple manufactured with materials of high purity gold (+ pole) and platinum (- pole) which has been commercialised by collaborative research with professor Goto from the College of Engineering in Tamagawa University.

It has smaller electromotive force drift and less uncertainty when measuring high temperature compared to using thermocouples manufactured with metal (R, S, B) and conforms to JIS C1602 (IEC60584).
