Time Constant of Temperature Sensor is an ideal equipment to study behaviour of sensors.

An electrically heated small heat source is supplied, its temperature is set and controlled by PID controller. There is a facility to mount temperature sensor on this. An ICE pot is also supplied. User can immerse sensor in this to measure low or zero-degree temperature. A digital Timer is supplied with the system for ease of noting observations/readings.
