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.
