The Vaisala TMP1 temperature probe is designed for demanding temperature measurements in industrial applications such as the pharmaceutical industry and calibration laboratories. The TMP1's IP66-rated housing makes it suitable for indoor or outdoor use. With a Pt100 RTD Class F0.1 IEC 60751 temperature sensor, the TMP1 offers a measurement range from -94 to +356°F (-70 to 180°C). Vaisala's thin-film capacitive technology allows for accuracy up to 0.18°F (0.1°C).

The Vaisala TMP1 is also part of the Indigo product family and compatible with Indigo 201 and 202 transmitters.
