RKI Replacement Hydrogen Cyanide (HCN) Sensor for the GX-3R Pro monitor. HCN is often a by-product of burning plastics and synthetic polymers. After plastics have burned, HCN will off-gas which makes monitoring HCN important for firefighters. A GX-3R Pro configured to 4-gas plus HCN makes an ideal solution for firefighters. The GX-3R Pro's HCN sensor has a range of 0 - 30.0 ppm.
To add one of the new sensors to a GX-3R Pro, the instrument firmware will need to be updated. This can be done by using the USB to IrDA adapter and following the IrDA Reprogramming instructions.

When ordering an individual sensor, make sure to also order the sensor's H2S scrubber at the same time. The HCN sensors utilize an H2S scrubber filter disk to eliminate any interference from H2S. When buying a new GX-3R Pro instrument, the scrubber filter disk is included.
