One Transmitter, Three Measurements
The Vaisala Combined Pressure, Humidity and Temperature Transmitter PTU300 measures barometric pressure in two accuracy classes, humidity, and temperature.
You can choose which probe best suits your needs: PTU301 for laboratories, PTU303 for outdoor use, the warmed PTU307 probe for demanding meteorology, and PTU30T for pressure and temperature only.

Vaisala Proven Sensor Technology
The PTU300 transmitter uses sensors known for their high accuracy and excellent long-term stability: the Vaisala BAROCAPAR is used for pressure measurement and the Vaisala HUMICAPAR for humidity measurement. The temperature sensor is a platinum RTD sensor
