WS-GP1 Weather Station

Delta-T

Compact all-in-one weather station
Highly portable
Unattended weather recording at remote and exposed sites
The WS-GP1 Weather Station has carefully matched high grade sensors able to measure rain, solar radiation, wind speed, wind direction, relative humidity and air temperature. The system comes complete with the powerful GP1 Data Logger and a 2m tripod mast.

Rapid installation
The WS-GP1 is supplied pre-wired and pre-programmed, making it an easy task to assemble the system, even in difficult environments. The system is delivered in two suitcase-style carry cases that can be used to store or transport the system. The cases are light enough for one person to carry on site.
Tough and dependable
Despite the low system cost, the sensors are dependable and suitable for use in demanding environments. The galvanised steel tripod and white painted stainless steel cross-arm ensure excellent physical strength. The internal battery provides 6 month’s operation (typical, for alkaline battery).
Easy data collection
Recorded weather data can be collected directly with a notebook PC, remotely by optional GSM modem, or alternatively by using a Pocket PC PDA running Pocket DeltaLINK Software. The PDA option makes it possible to collect and view the data, or reconfigure the logging set-up in the field. In addition to the standard logging options, the WS-GP1 can log and display wind rose, gusts, averages (including vector average) and maximum and minimum readings, with times of occurrence.

The WS-GP1 is an excellent choice for research or agricultural and environmental applications where reliable and accurate weather data is required.
