| | | One transmitter, three measurements he 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 he PTU300 transmitter uses sensors known for their high accuracy and excellent long-term stability: the Vaisala BAROCAP' is used for pressure metering and the Vaisala HUMICAP' for humidity measurement. he temperature sensor is a platinum RTD sensor. Graphical trend display he PTU300 series features a large | | numerical and graphical display, allowing users to easily monitor operational data, measurement trends and 1-year measurement history. he optional data logger with real-time clock makes it possible to generate over four years of measured history, and zoom in on any desired time or time frame. he battery backup of the real-time clock guarantees a reliable logging of measured data. | | Data collection and transfer to PC he recorded measurement data can be viewed on the display or transferred to a PC with Microsoft Windows' software. A USB-RJ45 cable makes it easy to connect the PTU300 to a PC. Flexible calibration A quick, one-point field calibration for humidity can easily be done using the Vaisala Hand-Held Humidity measuring device HM70. Serial communication he PTU300 comes with a standard RS-232 serial interface. he output format is compatible with major GPS receivers and NMEA coded messages. RS-485 is available as an option. Outdoor installation kit he optional HMT330MIK Installation Kit is available for outdoor installation. It provides reliable measurements for meteorological purposes. | | |
