Features/Benefits ▪ Barometric pressure, humidity, and temperature measurement in one transmitter ▪ Available with up to two barometric pressure sensors for added reliability ▪ RS232C serial interface with NMEA protocol for GPS use ▪ Graphical display and keypad for convenient operation ▪ Analog outputs, RS232/485, WLAN/LAN ▪ MODBUS protocol support (RTU/TCP) ▪ Optional universal power supply module ▪ NIST traceable calibration (certificate included) ▪ HMT330MIK installation kit for outdoor use ▪ Applications include environmental monitoring in calibration laboratories, industrial applications, GPS meteorology: estimating precipitable water vapor in the atmosphere, weather stations One Transmitter, Three Measurements The Vaisala Combined Pressure, Humidity and Temperature Transmitter PTU300 is a unique instrument measuring three parameters simultaneously. You can choose from the following probe options: PTU301 for laboratories, 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 The 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. Graphical Display of Measurement Data and Trends for Convenient Operation The 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 The PTU300 comes with a standard RS232 serial interface. The output format is compatible with major GPS receivers and NMEA-coded messages. An isolated RS485 is available as an option. The PTU300 is also capable of applying the MODBUS communication protocol and, together with an appropriate connection option, provides either MODBUS RTU (RS485) or MODBUS TCP/IP (Ethernet) communication. The data logger, with real-time clock and battery backup, guarantees reliable logging of measurement data for over four years. The recorded data 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 (W)LAN interface, which enables a (wireless) Ethernet connection. A USB service cable makes it easy to connect the 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.
