Rapid installation
The WS-GP1 Automatic Weather Station is supplied pre-wired and pre-programmed and can be set up on-site in minutes. 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.
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 system requires minimal maintenance.
The internal battery provides 6 month’s operation (typical).
Easy data collection
Recorded weather data can be collected directly with a notebook PC, or remotely by optional cellular modem. 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 GP1 Data Logger can store >600,000 readings.
The WS-GP1 Automatic Weather Station is an excellent choice for research or agricultural and environmental applications where reliable and accurate weather data is required.
