Vaisala has released a new generation barometric pressure, relative humidity and temperature transmitter series, the Vaisala PTU300.
The Vaisala PTU300 features digital measuring electronics for all three parameters, a range of sensor heads for the relative humidity and temperature measurements, calculated humidity variables and a new graphical display with backlight. The display shows three-hour graphical trends of sensor values and enables display of history data for up to 1 year. Vaisala PTU300 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.
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.
Applications for the PTU300 include environmental monitoring in calibration laboratories, GPS meteorology and weather stations.
