Description
The RKI ESR-X13P-OXY is a genuine RKI Oxygen (O2) replacement sensor designed for use in multiple RKI portable gas detection platforms.
RKI's 2026 replacement-parts documentation lists the ESR-X13P-OXY with an Oxygen range of 0–25% volume and identifies it for the RKI GX-3R, GX-3R Pro, GX-Force, GX-6100 and GX-9000.
This sensor is designed as a direct replacement for compatible instruments originally configured with the ESR-X13P-OXY Oxygen sensor.
Important: RKI uses several different Oxygen sensors across its instrument lineup. Verify the existing sensor part number and instrument configuration before ordering.

Important Range Note: RKI's 2026 individual replacement-part listings specify ESR-X13P-OXY as a 0–25% volume Oxygen sensor. A separate consolidated sensor table in the same price book lists 0–40% volume. This product listing follows RKI's repeated exact part-number replacement listings.
GasWatch 3 Note: RKI's consolidated sensor table specifically states that GasWatch 3 uses OS-BM2 for Oxygen. GasWatch 3 is therefore not included as compatible with ESR-X13P-OXY.
Verify the existing sensor part number before ordering.
