Features

• Barometric pressure, humidity, and temperature measurement in one transmitter
• RS-232C serial interface with NMEA protocol for GPS use
• Graphical display and keypad for convenient operation
• Analog outputs, RS-232/485
• Modbus RTU protocol support
• Traceable to international standards Vaisala Combined Pressure, Humidity and Temperature Transmitter PTU300 is a unique instrument measuring three parameters simultaneously. Options
• Available with up to two barometric pressure sensors for added reliability
• Optional universal power supply module
• HMT330MIK installation kit for outdoor use You can choose from the following probe options: PTU301 for wall mounting for example in laboratories or engine rooms, PTU303 for general use, PTU307 warmed probe for outdoor and demanding meteorology applications, and PTU30T for pressure and temperature measurement only. Proven Vaisala sensor technology PTU300 incorporates sensors known for their high accuracy and excellent long- term stability: Vaisala BAROCAPâ for pressure measurement and Vaisala HUMICAPâ for humidity measurement. The temperature sensor is a platinum RTD sensor. Graphical display of measurement data and trends for convenient operation PTU300 features a large numerical and graphical display with a multilingual menu and keypad. It allows users to easily monitor operational data, measurement trends, and access measurement history for the past 12 months. The optional data logger, with real-time clock, makes it possible to generate over four years of measurement history and zoom in on any desired time or time frame. The display alarm allows any measured parameter to be tracked, with freely configurable low and high limits. Versatile outputs and data collection PTU300 comes with a standard RS-232 serial interface. The output format is compatible with major GPS receivers and NMEA-coded messages. An isolated RS-485 interface is available as an option. PTU300 is also capable of applying the Modbus communication protocol, providing Modbus RTU (RS-485) communication. The data logger records data that can be viewed on the local display or transferred to a PC with Microsoftâ Windowsâ software. A USB service cable makes it easy to connect PTU300 to a PC via the service port. Outdoor installation kit Outdoor installation is possible using the optional HMT330MIK installation kit, for applications requiring reliable measurements for meteorological purposes. Flexible calibration Quick, one-point field calibration for humidity is easy using Vaisala Hand-Held Humidity Meter HM70. With Vaisala Barometric Pressure Transfer Standard PTB330TS, including optional humidity and temperature probe, field check and calibration can be performed for all three parameters.

Applications

• Environmental monitoring in calibration laboratories
• Industrial applications in semiconductor industry, engine testing and maritime sector
• GPS meteorology: estimating precipitable water vapor in the atmosphere, weather stations The display also shows the WMO pressure trend ΔP 3h and tendency of 0 … 8. Model Dimensions in mm PTU301 for wall mounting 12 (0.47) 120 (4.72) 169 (6.65) Ø 7 (0.2 183 (7.20) 116 (4.57) 96 (3.78)
