Vaisala Pressure, Humidity, and Temperature Transmitter PTU300


One instrument measures three parameters simultaneously: barometric pressure, humidity, and temperature.

1 INSTRUMENT, 3 PARAMETERS

Unique combination of a meteorological grade barometer combined with humidity and temperature measurement in a single, industrial-grade device. The instrument also has four different humidity probe options for various measurement needs. Reliable Vaisala HUMICAP® and BAROCAP® sensor technologies make it suitable for demanding meteorology applications and maritime conditions.

PROVEN SENSOR TECHNOLOGY

PTU300 incorporates sensors known for their high accuracy and excellent long-term stability: Vaisala BAROCAP® for pressure measurement and Vaisala HUMICAP® for humidity measurement. The temperature sensor is a platinum RTD sensor.  

LARGE GRAPHICAL DISPLAY

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 OUPUTS

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 and, together with an appropriate connection option, provides either Modbus RTU (RS-485) or Modbus TCP/IP (Ethernet) communication. The data logger records data that can be viewed on the local display or transferred to a PC with Microsoft Windows software. The transmitter can also be connected to a network with an optional LAN interface, which enables an Ethernet connection. 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.
