04 Series – Single Gas Monitors

The 04 Series single gas monitor is designed for long-lasting performance, featuring easily replaceable sensors and filters that ensure years of operation. Depending on the model, the 04 Series can run continuously for up to 9,000 hours using just two AAA-size alkaline batteries.

With three adjustable preset alarms, the 04 Series offers flexibility in alert settings. Moreover, it comes standard with visual, audible, and vibration alarms for added safety.

Replacement sensors for the 04 Series are both cost-effective and convenient to swap out in the field. They are also compatible with other popular RKI instruments like the GX-3R, GX-3R Pro, and GasWatch 3. 

Each 04 Series monitor is built to withstand impact, dust, and water, boasting an IP-67 ingress protection rating. These instruments are suitable for use in hazardous environments and are classified as intrinsically safe according to ATEX/IECEx standards, as well as complying with U.S. and Canadian standards for Class I, Division 1, Groups A, B, C, and D atmospheres.

This device can be worn on the wrist or a belt clip!
