The GP2 is a powerful 12 channel data logger that is easy to use, versatile, rugged and reliable. It can log most sensor types and accepts voltage, resistance, current, potentiometer, bridge, counter, frequency, and digital state inputs. DeltaLINK software helps the user set up logging sequences and provides control over reading frequency, sensor type, thresholds, units and much more. All Delta-T sensors can be selected from a menu.
The GP2 Data Logger features powerful controller functionality, and sophisticated programs can be easily created via a simple scripting editor. To learn more about the advanced features of the GP2 click on the blue button above.
Power and flexibility
As the user's needs change, the GP2 can adapt. Optional lids are available with additional cable entry points, dedicated Profile Probe inputs, or with wider diameter cable entry points.
The number of relay outputs can also be expanded - the standard GP2 has 2 relay channels but this can be increased to 6 with the optional Relay Expansion Module. The GP2 Data logger can also be networked with other GP2s (or a combination of GP2s and GP1 Data loggers).
The GP2 is the ideal data logger for field work, with applications ranging from agronomy, meteorology and hydrology to eco-physiology and soil science. We can supply complete systems including sensors, enclosures, solar power and communications options.
The GP2 Data Logger can log most sensor types and accepts voltage, resistance, current, potentiometer, counter, frequency, and digital state inputs.
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 statistical recording options for Average, Minimum, Maximum, Standard Deviation and more. Specialised wind options are available 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).
