    The RKI direct connect series gas sensors are highly reliable and very cost effective for the detection of common gas hazards. The direct connect series are available for LEL, Oxygen, H2S, and CO for a variety of RKI’s controllers. All sensors are explosion-proof with flame arrestors, and approved for use in hazardous locations.

    The tri-sensor head can be used either indoors or outdoors. The flame arrestors for the explosion-proof versions utilize a patented coating which make them water repellent. Also, splash guards are available for use in very wet environments.

    The unique tri-sensor design integrates 3 sensors into one explosion proof housing. This results in significant savings with installation and wiring cost versus traditional single sensor enclosures. Only one conduit needs to be run to the sensors.

    The tri-sensor head is designed to exclusively interface with the RKI Beacon 410 controller. This 3 sensor head, used with the Beacon 410, is especially well suited for wastewater applications.

    Also available in a two or four sensor version, with sensors for LEL, Oxygen, H2S, and CO available.

    IR (infrared) sensor versions available for LEL detection.
