Ion Science ARA Hydrogen Sulfide (H2S) Gas Detector

SKU: N/A

The ARA Hydrogen Sulfide (H2S) unit weighs only 92g and has a robust clip for attachment to workwear located close to the breathing zone. It was designed with practical applications in mind. 87mm in length means it won’t go in the way of workers moving around, making it ideal for restricted space maintenance on pipes or tankers. With a three-signal system comprising a flashing light, an audio alarm, and vibration to alert the wearer of exposure levels nearing harmful amounts, users may be confident that this model is safe in all circumstances.

There is a daily self-test feature on the ARA Hydrogen Sulfide gas detector to ensure that personnel is properly protected.

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.
