RKI GD-70D H2, 0-2.00% Vol., Ethernet & 4-20 mA in NEMA 4X


RKI GD-70D Sample Draw smart gas detection transmitter for Hydrogen (H2), 0-2.00% Vol. features a 4-20 mA & Ethernet Output Standard in NEMA 4X housing.

The long life high capacity pump and wide variety of sensing elements are replaceable in a few seconds, with no tools required! The smart sensors retain all calibration and sensor-specific data in non-volatile memory, so sensors can be hot-swapped in the field with no programming required. The sensors also retain calibration information, which means they can be conveniently calibrated separate from the transmitter, avoiding transport of calibration gases to the field location. The GD-70D firmware automatically corrects for long-term zero and span “drift” minimizing maintenance and maximizing reliability.

Please call Customer Service at 800-829-9580 if you have questions in choosing the correct product.

The GD-70D can be used as a stand-alone device, offering a number of communication protocols to existing PLC systems, or can be integrated with the Beacon 110, Beacon 200, Beacon 410, or Beacon 800 Controllers.

All GD-70D transmitters include a large, easy to read integral LCD display, tri-color bar graph for visual notification of alarm status, programmable low and high alarm relays, and fault relay. Pump flow is self-tuning for maintenance-free operation. Because all GD-70D base units are identical, sensors can be interchanged with no programming or tools required, resulting in maximum flexibility to the user.
