Temperature Sensor Pod

The A1-02b Temperature Sensor Pod is designed for measuring temperature at a remote site. Right out of the box, it will measure the ambient temperature. Additionally, the screw terminal connector can be used for hooking up a high accuracy RTD or thermistor temperature sensor. A separate miniature TC connector allows the addition of a Type T thermocouple for cryogenic temperature measurements.
