GD-70D Series Sample Draw Transmitter Gas Detector for Hydrogen Peroxide (H2O2) has a range on 0-3 ppm. 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.

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, like the H2O2 sensor replacement,  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.

Applications: Fumigation Disinfection of Medical Facilities, Pharmaceutical Environments, Cleanrooms, Production Filling Lines, and Chemical Fogging for the Food Industry
