ARA H2S Single Gas Detector
Portable Gas Detector from ION Science
Industrial sites in the Oil & Gas, Petrochemical and Offshore sectors can be volatile places if the right safety measures are not in place. You need dependable and ATEX certified gas detectors to keep the workforce safe.

About ARA H2S Single Gas Detector
Hydrogen Sulfide (H2S) may desensitise and render the body unconscious in no time at high concentrations, therefore, dependable personal monitoring equipment is crucial.
ARA H2S portable alarm is a low cost, wearable clip monitor for the detection of dangerous levels of Hydrogen Sulfide (H2S). The detector alerts workers when gas concentrations exceed set safety levels.
The ARA H2S clip monitor operates for 24 months maintenance-free, with continuous operation. The 36-month model, provides you with even more life for a competitive low-cost price, simply slip the detector into hibernation mode when you’re not using it to extend its service life, ideal for contractors who only visit site on occasion.
