Thermal Metrology

Thermal Calibration lab has facility for calibration of SPRTs and standard thermocouples probe and comparison calibration of all types of laboratory and industrial grade temperature measuring devices as per ITS-90. Quality system implemented in the laboratory is complying with ISO/IEC 17025: 2005.The laboratory is accredited by the National Accreditation Board for Testing & Calibration Laboratories (NABL), Department of Science and technology, Govt. of India. The laboratories also participate in the Proficiency Testing (PT) programs organized by the National accreditation body.

Comparison Calibration (-80°C to 1200°C)

The comparison calibration facility of thermal lab is well equipped with a range reference SPRTs, PRTs, TCs and dedicated digital temperature indicators. A range of highly stable heat sources like comparison baths, stirred alcohol & oil baths, dry block calibrators, thermocouple calibration furnace etc. can cover the temperature range from -80°C to 1200°C.

Temperature & RH Calibration (10% to 93% & 15°C to 45°C)

The relative humidity generator that measures and controls humidity with high accuracy working volume to accommodate most of the humidity probes, humidity-loggers/transmitters and hygrometers commercially available in industry for calibration. The reference standards maintained in the laboratory are traceable to national standards.
