A lack of proper safety precautions can make industrial sites in the Oil & Gas; Petrochemical; and Offshore sectors dangerous places. To ensure the safety of your employees, you need ATEX-certified gas detectors. A dependable personal monitoring device is essential when dealing with high amounts of hydrogen sulfide (H2S), which can quickly desensitize and knock a person out.
Wearable clip monitors for Hydrogen Sulfide (H2S) detection are inexpensive and easy to use (H2S). Workers are alerted if gas concentrations fall below predetermined safety standards. For 24 months, the ARA H2S clip monitor does not need to be serviced. When not in use, just put the detector into hibernation mode to extend its service life, which is great for contractors or consultants who only visit the site on a regular basis.
