Type of Instrument Estación Meteorológica
The instrument measures: Multiple Parameters
  • A powerful, rugged and highly flexible weather station
  • Unattended weather recording at remote and exposed sites
  • Designed for use in severe weather conditions
  • Wide choice of sensors, including soil moisture
  • GPRS modem communications 

The new advanced WS-GP2 Automatic Weather Station is based on the powerful GP2 Data Logger. It is an ideal solution for research and environmental monitoring applications. It provides a highly rugged and flexible system - users can select the optimal combination of sensors, logger, power and communications

The standard WS-GP2 includes sensors to measure rain, solar radiation, soil temperature, wind speed and direction, relative humidity and air temperature. 

The GP2 Data Logger has the power and flexibility to handle almost any environmental sensor, which means the WS-GP2 Weather Station can be as simple or as complex as your application requires. Even after installation, it's easy to adapt the system to your specific needs. Optional sensors include barometric pressure, soil moisture, soil EC, UV, PAR, albedo, net radiation, total and diffuse radiation, evaporation and surface wetness.

Data handling

Data can be easily collected by laptop via USB, or remotely using the GPRS modem options. Delta-T plans to introduce SDI options in the future. DeltaLINK Software makes it easy to set up recording intervals and to view and download stored data. 

Data presentation options include wind rose, gusts and average (including direction and vector average).

Advanced features for meteorology

For researchers interested in evapotranspiration, degree days, disease prediction, wind chill factor, dew point, PID control, etc. the GP2's advanced features will open up exciting possibilities.


The GP2's analog inputs can be fully customised. Each channel can have its own input type and recording parameters. DeltaLINK software gives the user control over reading frequency, thresholds and units, and provides recording options for average, min and max, plus specialised wind options - including wind rose, gusts and wind averaging

Users can add their own custom sensor types to the sensor library, exploiting the GP2's detailed configuration options. The GP2 provides 4 input ranges down to microvolt resolution with adaptive auto-ranging, excellent analog accuracy, and configurable sensor excitation - enabling it to support nearly all analog sensors.

Calculations based on the measurements from several input channels can be recorded and displayed as additional virtual channels (calculated measurements).

Script Editor 
This powerful software feature creates step by step operations to control simple or complex processes or recording requirements. The degree of sophistication it offers means the potential applications are numerous and varied. The editor interface is easy to use, no programming language is involved. 

  • Creates sequences of operations to implement models
  • Advanced control and recording capabilities
  • Easy user interface: no typing out of commands; no programming language
  • Implement simple or complex conditions, algebraic expressions and record result values

This unique software feature allows logging programs to be tested before real-world activation. For applications involving weather data, irrigation or soil moisture recording, the environmental variables can be changed to test how the program responds. Years of logging time can be simulated in just a few minutes. 

  • Implement simple or complex conditions, algebraic expressions and record result values
  • Create and manipulate variables e.g. for disease risk factor
