The new Model GD-70D smart gas detection transmitter series sets a new standard for performance, flexibility, and
versatility. The 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 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 field
locations. The GD-70D firmware automatically corrects for long-term zero and span “drift” minimizing maintenance and
maximizing reliability.

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 RKI’s Beacon series of single and multi-channel 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. NEMA 4X 115 VAC versions available.
