- SKU:
- ESR-B134-NH3
- MPN:
- ESR-B134-NH3
Description
The RKI ESR-B134-NH3 is a genuine RKI Ammonia (NH3) replacement sensor designed for compatible RKI GX-3R Pro and RKI SC-04 gas monitors.
The ESR-B134-NH3 provides an Ammonia measurement range of 0–400 ppm and uses electrochemical sensing technology for toxic gas detection.
RKI's 2026 replacement-parts documentation specifically identifies the ESR-B134-NH3 for the GX-3R Pro and SC-04.
Important: RKI offers multiple toxic-gas sensors for different instruments and configurations. Verify the instrument model, installed sensor and required gas range before ordering.
