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, H2 Specific LEL, Oxygen, H2S, and CO for a variety of RKI's controllers. All sensors are explosion-proof with flame arrestors, and approved (optional non-explosion proof version available for oxygen for use in hazardous atmospheres).
The direct connect sensors can be used in two different ways. The sensors can be mounted directly to the controllers as a complete stand alone system, or they can be mounted to explosion proof junction boxes for remote detection.
