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.

SPECIFICATIONS:

1.  A digital mV Meter and a digital temperature indicator with 

Two different type of thermocouples.

2.  A water container with heater of 1 KW.
