04 Series

04 Series Single Gas Detectors

Smallest Toxic Gas Monitor

The 04 Series toxic single gas monitor is the smallest toxic gas monitor designed to operate for many years with field replaceable sensors and filters. The HCN, NO2, PH3, and SO2 versions can be operated continuously for at least 3,000 hours on (2) AAA-size alkaline batteries. The 04 models have 3 preset alarms that are user adjustable. Each version is also equipped with visual, audible, and vibration alarms as standard.

Each 04 Series monitor is impact, dust, and water-resistant with an IP-67 ingress protection rating. 04 Series instruments are safe for use in hazardous locations, classified as intrinsically safe ATEX/IECEx and by QPS to U.S. and Canadian standards for Class I, Division 1, Groups
A, B, C, and D atmospheres.
