RKI Hydrogen Cyanide (HCN), 0-30 ppm, for GX-3R Pro & SC-04 Replacement Sensor
- SKU:
- ESR-A13D-HCN
- MPN:
- ESR-A13D-HCN
Description
The RKI ESR-A13D-HCN is a genuine RKI Hydrogen Cyanide (HCN) replacement sensor designed for compatible RKI GX-3R Pro and RKI SC-04 gas monitors.
The ESR-A13D-HCN provides a Hydrogen Cyanide measurement range of 0–30 ppm and uses electrochemical sensing technology for toxic gas detection.
RKI's 2026 replacement-parts documentation specifically identifies the ESR-A13D-HCN for the GX-3R Pro and SC-04.
Important: RKI offers multiple toxic-gas sensors with similar designs and part numbers. Verify the instrument model, installed sensor and required gas range before ordering.
