PRT Platinum Resistance Reference Thermometer. Temperature Standard.
Platinum Resistance Thermometers (PRT's) for use in every application from standards calibration to site temperature measurement.
If our 'off the shelf' range will not suit your needs we are able to supply custom manufactured thermometers to almost any specification.
Thermometers can be supplied calibrated or uncalibrated.
Calibration is normally carried out in laboratory which is registered under the United Kingdom NAMAS scheme.
However calibration can be arranged to suit your particular needs.

Model  Description 
PRT T100  Platinum Resistance Reference Thermometer.

The cells now offered have been increased in purity and length to conform to the requirements of optimal realizations except that we have sealed in 1 atmosphere of 6N pure argon at the freeze temperature for you.

Sealed optimal realizations of ITS-90 are made from metal exceeding 6N5 purity and have a useable depth below the metal surface of more than 200mm.
They come complete with Inconel basket, a carry case and the necessary heat shunts and reflectors to enable them to fit into our apparatus.
