Thermocouple Calibration Test Rig Manufacturer,Supplier and Exporter in India
Product Code : EL-HTL-10055
Jlab Export is a leading Thermocouple Calibration Test Rig Manufacturer,and suppliers in India
Thermocouple Calibration Test Rig (code EL-HTL-10055) is a bench unit for calibrating a thermocouple over 0 °C to 100 °C against two fixed points, melting ice and boiling water. A digital mV meter shows the thermocouple voltage, a digital temperature indicator shows the reading, and a water container with a 1 kW heater provides the boiling point. JLab makes this thermocouple calibration rig in Ambala, India.

Calibrating at the Ice and Boiling Points
The thermocouple tip goes first into melting ice and then into water boiled by the heater. The indicator is adjusted and the two dips repeated until it reads 0 °C in ice and 100 °C in boiling water, which sets a straight-line calibration between the two points. Crushed ice mixed with a little water gives a steadier ice point than dry cubes. Water boils at exactly 100 °C only at standard atmospheric pressure, so in a hilly location or on a low-pressure day the boiling point is slightly lower and the upper point should be corrected from the barometric pressure.
What the mV Meter Shows
By the Seebeck effect, a junction of two dissimilar metals produces a small emf that rises with the temperature difference between the measuring junction and the reference junction. Reading the mV meter at the ice and boiling points gives the change in emf over a 100-degree span, and dividing gives the average sensitivity in microvolts per degree. The two thermocouples supplied are of different types, so the same span produces different voltages from each, which shows why an indicator must be set for the thermocouple type it reads. Over 0 °C to 100 °C the emf curve of common types is close to straight, which is why a two-point linear calibration serves this range.
Thermocouples and Thermocouple Trainers
- Type K Thermocouple — nickel-chromium and nickel-alumel thermocouple with a wide temperature range.
- Copper Constantan Thermocouple — copper-constantan pair with two terminals, mounted on a stand.
- Thermocouple Trainer Kit — K-type thermocouple with an on-board amplifier and panel meter, up to 100 °C.
This rig is grouped with the temperature and heat flow benches in Heat Transfer Lab, within Engineering Lab Equipment.
