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

• Liquid Nitrogen (-196.075 °C) CMC: 0.0084°C
• Triple Point of Water (0.01°C) CMC: 0.0018°C
• Freezing Point of Indium (156.598°C) CMC: 0.0030°C
• Freezing Point of Tin (231.928°C) CMC: 0.0032°C
• Freezing Point of Zinc (419.527°C) CMC: 0.0046°C
• Freezing Point of Zinc (419.527°C) CMC: 0.0046°C
