Testing a Thermistor

Because thermistors are simply resistors, its easy to test it out. Simply measure the resistance using a multimeter:

You should read about 10Kohm assuming its room temperature where you're sitting. The resistance of course may be higher or lower depending on the room temperature. Also, your hands may end up touching the contacts so your body-resistance will lower the value a bit too. But you should still get about 10 Kohm

For example, its warm here in an un-airconditioned room in the middle of the summer, so we read 8Kohm (30°C - 86°F!)
