Chlorine (Cl2) Detectors

We supply a wide range of fixed and portable chlorine gas detectors to provide both facility-wide protection and personal safety. Fixed systems deliver constant monitoring in industrial plants, while portable detectors give workers mobility and protection in changing environments.

Our chlorine detectors come from leading manufacturers including BW, Honeywell, Crowcon, Dräger, GMI, MSA, RAE Systems, Senko, and Uniphos. Portable models are rugged and lightweight for field use, while fixed systems are engineered for seamless integration into industrial safety infrastructures. Portable detectors may also be available for hire.

Protect staff and maintain safe operations in water treatment, chemical processing, and industrial plants with our fixed and portable chlorine detection systems.

Detection is achieved using electrochemical sensors, which provide fast response times, high sensitivity, and stable readings across workplace exposure limits. Routine calibration ensures dependable performance and compliance with international safety standards.

Chlorine (Cl₂) is a toxic, corrosive gas commonly used in water treatment, chemical production, and the manufacture of plastics and solvents. Although vital in many industries, chlorine exposure poses significant health risks, including eye and respiratory irritation at low concentrations, and potentially life-threatening effects at higher levels. Because chlorine is heavier than air, it can accumulate in low-lying areas, making continuous monitoring essential wherever the gas is used or stored.
