RKI Carbon Dioxide (CO2), 0-5,000 ppm, for S2 & M2A-XL IR Explosion-Proof Direct Connect Replacement Sensor
- SKU:
- 61-0191RK-02
Description
The RKI 61-0191RK-02 is a genuine RKI infrared detector designed for measurement of Carbon Dioxide (CO2) from 0–5,000 ppm. It features an explosion-proof direct-connect design for compatible RKI fixed gas detection systems.
The 61-0191RK-02 uses infrared (IR) sensing technology for carbon dioxide monitoring. This version is supplied as the detector/sensor assembly only and does not include a transmitter or junction box.
RKI lists the 61-0191RK-02 as a replacement sensor for compatible Explosion-Proof S2 Series and Explosion-Proof M2A-XL Series systems.
Important: The sensing element within this explosion-proof detector is not a separately replaceable plug-in sensor. If sensor replacement is required, the complete 61-0191RK-02 detector assembly is replaced.
RKI offers several 61-0191RK CO2 detectors with different measurement ranges. Always verify the complete RKI part number and required CO2 range before ordering.
