Thermostat.

Negative Temperature Coefficient Thermistor Test.

Tested the resistance by measuring the resistance between terminals of the thermistor by heating water up at different temperatures ranging from 15-80 Degrees Celsius using a thermometer to determine the heat. Then testing the thermistor's resistance with a multimeter at each point going up in temperature 15,20,30,40,50degrees...etc

Manufactures specs: Cold= 2000-3000ohms. Hot= 200-400ohms

My results were well in specifications as when the water was only 15deg. the thermistor showed high resistance (2.95k ohm's) and when the water was 80deg. I got a reading of only (.360k ohm's) this shows the thermistor was working upto scratch and would operate with no problems.
Results show:

  1. It would have been nice for you to explain what type of thermistor this is and how that affects it operation. Just as a note a thermostat is not a thermistor.
