RKI Replacement NO2 Sensor ESR-A13D-NO2

RKI Replacement Nitrogen Dioxide (NO2) Sensor for the GX-3R Pro monitor has a range of 0 - 20.0 ppm. NO2 is is commonly generated from the burning of fuel, especially diesel fuel. 

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 NO2 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.
