The Riken Keiki GD-70D smart gas detection transmitter series sets a new standard for performance, flexibility, and versatility. The Riken Keiki GD-70D sample-draw transmitter offers an array of sensor technologies unmatched in the industry, including unique offerings, such as our hydrogen-specific or LEL versions.

The long-life high capacity pump and the 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 that sensors can be hot-swapped in the field with no programming required. The sensors also maintain calibration information, which means they can be conveniently calibrated separate from the transmitter, avoiding transport of calibration gases to the field location. The Riken Keiki GD-70D firmware automatically corrects for long-term zero and span “drift” minimising maintenance and maximising reliability.

The GD-70D can be used as a stand-alone device, offering some communication protocols to existing PLC systems, or can be integrated with RKI’s Beacon series of single and multi-channel controllers.

All GD-70D transmitters include a large, easy to read integral LCD, tri-colour 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.
