FAQ

Q1: What is the function of a chlorine dioxide gas sensor? ❯

Chlorine dioxide (ClO₂) is a highly oxidizing gas widely used in drinking water disinfection, food processing, and pulp and paper industries. However, it is irritating and corrosive, and exposure above safe levels can harm the respiratory tract and eyes. Chlorine dioxide gas sensors continuously monitor ClO₂ concentrations in the air, triggering alarms when levels exceed safety thresholds to protect personnel health and ensure production environment safety.

Q2: Where are chlorine dioxide gas sensors suitable for use? ❯

Chlorine dioxide sensors are widely deployed in water treatment plants, swimming pool disinfection systems, paper mills, food processing facilities, laboratories, and gas cylinder storage rooms or pipeline areas. In these settings, ClO₂ is commonly used as a disinfectant or bleaching agent.

Q3: How should chlorine dioxide sensors be maintained? ❯

To ensure detection accuracy and service life, users are advised to perform regular calibration with calibration gas, typically every 6-12 months. During routine use, avoid prolonged exposure to high ClO₂ concentrations to prevent premature failure. Keep the gas sensor probe clean, prevent dust and moisture ingress, and operate within the temperature and humidity conditions specified in the manual.
