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.

Flexible Calibration

Quick, one-point field calibration for

humidity is easy using the 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.
