High quality thermistor based temperature sensor

Thermistor based sensors

Modern high accuracy thermistors have several advantages for recording environmental temperatures. They are sensitive generating large resistance changes for small changes in temperatures this means that the attached electronics can be less sensitive and therefore less 'expensive'. Thermocouples can measure temperature over a greater range but are generally less accurate in ambient temperatures, platinum based sensors provide the best accuracy but they are expensive and require an expensive 3 or 4-wire solution for greatest accuracy. Thermistors are popular in research and in medical applications, e.g as electronic medical thermometers. The thermistors themsleves are small and relatively robust ours come either mounted in a waterproof stainless steel tube or we can supply unmounted thermistors for you to make your own sensors. These unmounted thermistors are only 2.5mm. across so can measure temperature in fairly small spaces.

Type 1 Thermistor based sensor

For use with logger models 4R (RS-232) & RVIP (RS-232).

Available with 1m, 2m, 5m & 10m lead lengths with the sensor mounted in a stainless steel tube.

Type 2 Thermistor based sensor

For use with logger model 4Therm (USB).

Available with 1m, 2m, 5m & 10m lead lengths with the sensor mounted in a stainless steel tube. Also available unmounted for making your own sensors.
