AT THERMISTOR
The AT thermistor is a high-precision thermal
sensing device featuring extremely small
B-value tolerance and resistance.
When used as a temperature gauge, the AT
thermistor requires no adjustment between
the control circuit and the sensor.
This insures temperature precision of
Temperature indicators and control instruments
are now available for use with the thermistor.
