Gill MetPak RG Base Station

£0.00 exVAT

£0.00 incVAT

This MetPak RG Base Station allows an ARG314 tipping bucket rain gauge to be added and positioned remotely to the four standard parameters: temperature, relative humidity, barometric pressure and dew point. Plus, a Gill WindSonic 1 ultrasonic wind speed and direction sensor with mounting bracket and 6m cable can also be included.

Please call our office to find out about alternative solutions.


The MetPak RG Base Station measures barometric pressure, air temperature, humidity and dew point. Precipitation measurements can be added to those parameters provided with an ARG314 rain gauge, delivering reference quality rainfall measurements. The separate ARG314 rain gauge comes complete with a base plate and 6m of cable and is calibrated to the MetPak ensuring excellent accuracy and data quality.

Wind speed and direction can also be added with an optional Gill WindSonic 1 ultrasonic sensor that comes ready to integrate with the base station. Mounting bracket and 6m cable are included.

The MetPak RG Base Station utilises a highly accurate barometric pressure sensor and a Rotronic Hygroclip HC2-S3-GI temperature/humidity probe. The design of the MetPak allows measurements to be as accurate as possible without influencing other measured parameters yet provides a compact, reference quality system. The unit is especially suitable for harsh or marine environments and is supplied with selectable Gill ASCII, NMEA SDI-12 and Modbus outputs.

The following parameters come as standard:
• Air Temperature
• Relative Humidity
• Barometric Pressure
• Dew Point
• Optional ARG314 rain gauge, base plate and 6m cable
• Optional wind speed & direction with mounting bracket and 6m cable

MetPak RG Base Station comes complete with: MetSet configuration software, MetView data logging/visualisation software, mounting kit to adapt to poles or masts and selectable ASCII, NMEA, SDI-12 or Modbus outputs.

Richard Paul Russell Ltd. can connect the sensor to the website where data can be viewed using any internet connected device and downloaded for detailed analysis in a .CSV file format.
