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