RKI Combustible Gas (LEL), 0-100% LEL, Catalytic Direct Connect Replacement Sensor
- SKU:
- 61-0140RK
Description
The RKI 61-0140RK is a genuine RKI catalytic detector designed for monitoring combustible gases from 0–100% LEL in compatible RKI fixed gas detection systems.
The sensor uses catalytic oxidation technology and responds to a broad range of flammable gases and vapors. It features a direct-connect design and is supplied as the detector/sensor only, without a transmitter or junction box.
The 61-0140RK is the UL version of this detector. RKI documentation identifies it for compatible Direct Connect systems, M2A systems, S-Series equipment, and the 65-2481RK Multi-Point Detector.
Important: This is the standard 0–100% LEL combustible version. It should not be confused with the 61-0140RKA, which is designed for PPM and low-LEL combustible gas applications, or the 61-0140RK-05 CSA/cCSAus version.
