Chlorine Dioxide (ClO2) Detectors

We provide a range of fixed and portable chlorine dioxide gas detectors for both facility-wide monitoring and personal worker protection. Fixed systems ensure continuous surveillance in plants where ClO₂ is produced or applied, while portable detectors offer mobility and safety for staff operating in variable or high-risk areas.

Our product range includes detectors from leading manufacturers such as BW, Honeywell, Crowcon, MSA, RAE Systems, and Uniphos. Portable units are lightweight and durable for field use, while fixed detectors integrate seamlessly into plant safety infrastructures. Portable detectors may also be available for hire.

Protect your staff and maintain operational safety in water treatment, food processing, and industrial applications with our fixed and portable chlorine dioxide detection systems.

Detection is achieved with electrochemical sensors, engineered for rapid response and accurate measurement across workplace exposure limits. Routine calibration maintains accuracy, ensuring long-term reliability in demanding applications.

Chlorine dioxide (ClO₂) is a powerful oxidising agent used in water treatment, pulp and paper processing, and food sanitation. Despite its effectiveness in disinfection, chlorine dioxide is highly toxic and can cause irritation to the eyes, skin, and respiratory system. At elevated concentrations, it can lead to serious health complications, making reliable detection essential in industrial and processing environments.
