Outdoor temperature probe


The PTT-331 range are direct output, temperature sensors for measuring outside air temperature. Units contain either a high quality thermistor, Nickel or Platinum sensing element. The sensors are housed in IP65 rated enclosures.

The PTT-331 has a cap containing the sensing element located externally in the shadow of the lid to curb the effects of solar gain, but should always be situated in a sheltered position on a north facing wall.


- IP65 Protection Index
- Wide range of types of sensing elements
- Radiation shield version to minimize gain errors on the effects of direct sunlight


- Hinged lid with tamper proof facility
- Sensor consistency with other Priac products
