Pressure, humidity and temperature measurement

Vaisala has introduced a new generation barometric pressure, relative humidity and temperature measuring transmitter series, the Vaisala Combined Pressure, Humidity and Temperature Transmitter PTU300.

The PTU300 features fully digital measuring electronics for all three parameters, several small RH&T sensor heads for different applications, calculated humidity variables, and a new graphical display with backlight. The display shows three-hour graphical trends and a history for one year. It also has seven language options.

The PTU300 has four different probe options: PTU301 for laboratories, PTU303 for outdoor use, the warmed probe PTU307 for demanding meteorology, and PTU30T for pressure and temperature measurement only.

Applications for the PTU300 include environmental monitoring in calibration laboratories, GPS meteorology; and weather stations.

The PTU300 transmitter uses the Vaisala BAROCAP sensor for pressure measurement and the Vaisala HUMICAP sensor for humidity measurement. The temperature sensor is a platinum RTD sensor.
