Chlorine (Cl2) Gas Sensor, 0-10ppm/0-5000ppm

Chlorine sensors typically operate on electrochemical principles. The sensor contains an electrolyte and electrodes. When chlorine gas in the air enters the sensor, a redox reaction occurs on the electrode surface, generating an electrical signal proportional to the gas concentration. This electrical signal is amplified and converted to yield the chlorine concentration value.

Chlorine gas sensors are widely used in production, transportation, and application sites involving chlorine. Examples include chlor-alkali plants, drinking water and wastewater treatment facilities, bleach manufacturing, the paper industry, and laboratory environments. By continuously monitoring chlorine levels, sensors help personnel promptly detect leakage risks, preventing personnel poisoning or equipment corrosion.

When operating Cl2 sensors, prolonged exposure to high-concentration environments should be avoided to prevent premature sensor degradation. Regular calibration is essential to maintain detection accuracy, and electrolyte or filter membranes must be replaced according to manufacturer specifications. Storage environments should avoid high temperatures, humidity, or corrosive atmospheres to preserve performance. Installation locations should prioritize well-ventilated areas and avoid stagnant zones.
