.. ET THERMISTOR The ET thermistor is smaller version of the AT thermistor. Its fast response time and high reliability makes it particularily suitable for use in medical equipment and thermometers. Manufactured by a full-automated production line, all ET the thermistors have identical size and that maks it possible to assemble sensors automatically.
