The GP2 has unique reliability built on Delta-T’s 25 years’ experience in designing and manufacturing data loggers. Ease of use Simple point and click software makes it easy to configure channel...

GP2 Data Logger Expansion An expansion lid is available with additional cable entry points and configurations or wider diameter cable entry glands. The number of programmable control relay outputs can be increased from 2 to 6 using the optional Relay Expansion Module. Up to 7 GP2 Data Loggers can be networked to create complex monitoring and control systems. Storage, communication & power 4 MB of FLASH memory enable storage of 2.5 million readings (typical). Data can be collected by laptop locally via USB/RS232 or remotely using the cellular modem options. The GP2 has 6 alkaline AA internal batteries...

The GP2 Data Logger is SDI-12 enabled The GP2 Data Logger supports SDI-12 sensors. Since March 2016 all GP2s have SDI-12 as standard, and earlier GP2s can be easily updated via a software download at www.delta-t.co.uk • Huge additional input capacity for SDI-12 sensors • Existing analog and digital channels fully available • Highly flexible logger + sensor networks • Free of charge upgrade – comes as standard with new GP2s Ease of Use • Seamless integration into GP2 Program Editor, facilitating construction of sophisticated calculations and other operations from SDI-12 measurements • Unusually...

The GP2 firmware takes care of scheduling (including power switching) and issuing the necessary commands to ensure that results are available for the program to process when required. DeltaLINK’s ‘Read Now’ feature provides additional on-demand readings, in real time, for commissioning and diagnostic use - and for reassurance that an installation is functioning as intended. A field-attachable connector for SDI-12 interconnects with the rugged Delta-T M12 5-way sensor/RS232 cabling system. The interchangeable extension cables and Tconnectors allow an SDI-12 bus to be easily assembled - and also...

Cloud-based data sharing platform DeltaLINK-Cloud is a sophisticated and secure online data viewing, management and sharing platform for Delta-T Devices data loggers. Connect and upload, then monitor, organise and share your sensor data with ease. Live data can be viewed remotely on mobile devices via animated dashboards. DeltaLINK-Cloud Dashboards Display selected data using simple graphical devices known as widgets. With dashboards, you can control the type, colour and position of widgets, ensuring that critical data is displayed clearly and with maximum impact. These high quality data visualisations...

East Malling Research Precision Irrigation experiments and commercial crop trials In early 2012 world-renowned horticultural research institute East Malling Research (EMR) identified a requirement for a sophisticated and reliable Data Logger and Controller - for application in a number of challenging long-term research and commercial trial projects. The projects are on-going and focus on the cultivation of substrate-grown soft fruit crops, and the effects that precision automated irrigation treatments have on marketable yields and quality of fresh produce. EMR selected the GP2 Data Logger and...
