A hydrogen sulfide detector, or H2S detector, is used for protection in hazardous gas environments. Tanks, silos and tunnels are examples of worksites with an enlarged risk of unhealthy amounts of the hazardous H2S gas. WatchGas provides companies that work in these industries with high-end equipment based on the needs and input from our customers.

How does a H2S detector work?

Hydrogen sulfide is a colorless gas that can cause serious health issues when exposed to it. Therefore, it is important to occupy your employees or your worksite with either a fixed or portable H2S detector. The hydrogen sulfide detector will record the level of H2S and set off an alarm when the H2S levels pass certain thresholds. When the gas detector goes off, it alerts your employees to take immediate action, such as evacuating the area of wear protective gear. As a gas detection manufacturer, we secure a safe workplace with our equipment.
