AT THERMISTOR
The AT thermistor is a high-precision thermal
sensing device featuring an 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 a temperature precision of 60.38
C.
Temperature indicators and control instruments
are now available for use with the thermistor.
