Thermal Calibration
Fixed points are most accurate devices available for defining a temperature scale. Fixed point cells are designed to realize the liquid-solid equilibrium temperatures of certain high purity metal elements, for calibration of thermometers at ITS-90 fixed points.
Lawkim has facility to calibrate SPRT/PRT by primary method (fixed point cell). Apart from Lawkim offer calibration of various sensors, oven, autoclaves, chambers for temperature and humidity parameters and covering range (-) 196°C to +1200°C
We Calibrate SPRT/PRTS/ THERMOCOUPLES by fixed point cell for following points:
