Resistance Thermometry

rt1Resistance Thermometry Laboratory has developed high accuracy capability to support national temperature measurement activities. The laboratory also responsible to ensure all Resistance Thermometry measurement in the country meet and comply with the International Temperature Scale-1990.

The photos illustrate the traceability for Resistance Thermometry measurement in Malaysia.
