Thermocouple calibration test rig:
The unit helps in calibrating given thermocouple for the range 0°c to 100°c. While calibrating, thermocouple is once dipped in ice for 0q c and then in boiling water for 100°c. This is done till the thermocouple shows the actual temperature of ice (0° c) and boiling wafer (100°c) and a linear calibration is set. A mv meter is provided to know the corresponding voltage.
A digital mv meter and a digital temperature indicator with 2 different type of thermocouples.
A technical manual accompanies the unit.
