RKI Methane (CH4), 0-9,000 ppm, for M2A & M2A-XL Catalytic Direct Connect Replacement Sensor
- SKU:
- 61-0140RKA
Description
The RKI 61-0140RKA is a genuine RKI catalytic detector designed for Methane (CH4) measurement from 0–9,000 ppm in compatible RKI fixed gas detection systems.
This detector is designed for PPM and low-LEL combustible gas applications and uses catalytic sensing technology. It is a direct-connect detector supplied without a transmitter or junction box.
RKI documentation specifically identifies the 61-0140RKA as the catalytic detector used with the M2A 65-2647RK and M2A-XL 65-2647XL Methane 0–9,000 ppm transmitter configurations.
Important: This is the UL version of the RKI 61-0140RKA detector. The 61-0140RKA-05 is the corresponding CSA/cCSAus version. This sensor should also not be confused with the standard 61-0140RK combustible detector used for 0–100% LEL applications.

RKI documentation specifically identifies the 61-0140RKA for the following transmitter configurations:
- RKI M2A 65-2647RK – Methane (CH4), 0–9,000 ppm
- RKI M2A-XL 65-2647XL – Methane (CH4), 0–9,000 ppm
Important: Several RKI catalytic detectors have similar part numbers but are intended for different ranges or certification versions:
- 61-0140RKA – Methane (CH4), 0–9,000 ppm, catalytic, UL version
- 61-0140RKA-05 – Methane (CH4), 0–9,000 ppm, catalytic, CSA/cCSAus version
- 61-0140RK – Combustible gas, 0–100% LEL, catalytic, UL version
- 61-0140RK-05 – Combustible gas, 0–100% LEL, catalytic, CSA/cCSAus version
Always verify the complete RKI part number, required measurement range, certification version, and instrument configuration before ordering.
