Description
The PureAire Universal Chlorine Dioxide (ClO2) Gas Detector is a fixed gas monitoring system designed for continuous detection of chlorine dioxide in water treatment, wastewater treatment, industrial, chemical processing, laboratory, and other applications where ClO2 may be present.
This chlorine dioxide configuration is available in 0–1 ppm and 0–3 ppm detection ranges. PureAire's Universal Gas Detector provides continuous, real-time monitoring using renewable electrochemical sensor technology.
The monitor features a local digital display, built-in audible alarm, visual alarm indicators, two adjustable alarm relays, and an active 4–20 mA output for integration with PLCs, building automation systems, ventilation systems, remote alarms, and other facility safety equipment.
PureAire's Universal platform uses a renewable electrochemical sensor cell designed for long-term service and maintainability. The sensor stores calibration information to support ongoing maintenance of the monitoring system.
