GP-DU SDI-12

GP-DU (for Analog Sensors)

The GP-DU handheld reader gives immediate readings of current measurement conditions from GroPoint sensors. It also allows testing of individual sensors to troubleshoot when the sensors are part of a larger system. It features a large display window in a robust weather resistant casing with a 3 pin EN3 connector.

The GP-DU reads data from analog sensors and displays the volumetric moisture content as a percentage.

The GP-DU SDI-12 is capable of reading all GroPoint SDI-12 sensors. Alternatively, it can be used to read data directly from a GP-DL4 SDI-12 data logger.
