| The
Temperature calibration facility was established with the sole aim to calibrate and
standardize RTDs and thermocouples of high and low temperature range for a variety of
industries ranging from power plants, steel plants, foundry units, heat treatment shops to
several other small scale industries. |
|
|
- Calibration of thermocouples, devices and temperature measuring instruments from ambient
temperature to 1450 degree Celcius
Master Sensors:
- Type S Thermocouple (Scandura, Italy)
- Type S Thermocouple (ISOTECH, UK)
- SPRT (NPL, India)
- PRT (Scandura, Italy)
