RKI Carbon Monoxide (CO) / Oxygen (O2), 0-300 ppm / 0-25% Volume, for GasWatch 3 & CX-04 Combo Replacement Sensor
- SKU:
- ESR-X1DP-CX
Description
The RKI ESR-X1DP-CX is a genuine RKI combination Carbon Monoxide (CO) and Oxygen (O2) replacement sensor designed for compatible RKI GasWatch 3 and RKI CX-04 gas monitors.
This combination electrochemical sensor provides both CO and O2 detection in a single sensor assembly. RKI's 2026 replacement-parts documentation specifies a Carbon Monoxide range of 0–300 ppm and an Oxygen range of 0–25% Volume.
RKI identifies the ESR-X1DP-CX for the GasWatch 3 and 04 Series, with the 04 Series application specifically corresponding to the CX-04 CO/O2 dual-gas monitor.
Important: Verify the existing sensor part number and instrument configuration before ordering. RKI offers several combination and individual CO/O2 sensors with different compatibility and specifications.
