103AT-11
HIGH PRECISION THERMISTOR AT THERMISTOR AT-11,AT-2 AT-4 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 Ϯ0.3ЊC. Temperature indicators and control instruments are now available for use with the thermistor.
