Thermal Calibration Laboratory

Sigma Test & Research Centre is a NABL accredited thermal calibration laboratory, having a facility of RTD’s, SPRTs, HTPRTs, standard Thermocouple probes and all types of industrial and laboratory-grade temperature measuring devices.

STRC has an operating range of -80°C to 1200°C and 20% RH to 94% RH with the best available CMC as per ISO 17025:2005.

Our state-of-the-art calibration facility is equipped with a range of references SPRTs, PRTs, TCs dedicated digital temperature indicators.

Digital Thermohygrometer and range of highly stable heat sources like Dry block calibrators, oil & alcohol baths, Thermocouple calibration furnace and zero-point well etc.
