A chlorine gas sensor is an electronic device that continuously monitors the concentration of chlorine (Cl₂) in the air. It detects chlorine’s presence through electrochemical reactions that produce a measurable signal. Chlorine is highly toxic even at low levels—making precise detection essential for industrial, chemical, and water treatment operations. By continuously monitoring air quality, the chlorine gas detector helps prevent accidental exposure, ensuring worker safety and regulatory compliance.
The standard test for chlorine gas involves using damp blue litmus paper. When exposed to chlorine, the paper first turns red due to acidity, then becomes white as chlorine bleaches it—confirming the gas’s presence.
Chlorine gas acts as a potent irritant and oxidizing agent. It can damage the respiratory tract, eyes, and skin. Historically used in warfare, today its controlled industrial use requires robust chlorine gas detection systems to prevent harmful exposure.
Chlorine gas can be detected using advanced chlorine gas detectors or portable chlorine sensors. These instruments use electrochemical sensors to detect Cl₂ molecules and trigger alarms when concentrations exceed safe thresholds.
In the UAE and GCC, industries such as water desalination, chemical processing, and semiconductor manufacturing heavily rely on chlorine. To ensure workplace safety and meet global standards, chlorine gas detection systems are crucial. With Dubai and Abu Dhabi’s push toward sustainable and safe industrial expansion, these detectors support the region’s vision of world-class occupational safety and environmental protection.
