Benefits:
What sets the 04 Series apart is its cost-effective, field-replaceable sensors and filters, which can be swapped easily. These sensors are compatible with other popular RKI instruments such as the GX-3R, GX-3R Pro, and GasWatch 3. With a sensor lifespan exceeding 3 years and a 3-year warranty*, reliability is assured.
Additionally, the 04 Series is built to withstand impact, dust, and water, boasting an IP-67 ingress protection rating. It is safe for use in hazardous locations, classified as intrinsically safe according to ATEX/IECEx standards and certified by QPS for U.S. and Canadian standards for Class I, Division 1, Groups A, B, C, and D atmospheres.
