Chlorine Dioxide Gas Detector

$2,170.00

Product Summary

The PureAire Chlorine Dioxide Fixed Gas Detector is a trusted solution for facilities that require continuous monitoring of chlorine dioxide (ClO₂) gas. Designed to work with a dedicated, renewable toxic gas sensor calibrated to detect ClO₂ in parts-per-million (ppm), this detector delivers real-time accuracy and reliable safety monitoring.

Chlorine dioxide is used in a variety of industries, including pulp and paper bleaching, water and wastewater treatment, food processing sanitation, and select semiconductor manufacturing applications where it may be used for precision cleaning and oxidation processes. Because ClO₂ is a potent oxidizer and toxic inhalation hazard, real-time gas detection is critical for ensuring worker safety and regulatory compliance.

PureAire’s chlorine dioxide sensors are engineered to last up to 8 years under typical operating conditions. They are rechargeable with on-site electrolyte replacement, providing a cost-effective solution that minimizes maintenance and downtime.

For any facility working with chlorine dioxide—including high-tech and industrial operations—PureAire offers a reliable, low-maintenance gas detection system designed to protect people, equipment, and production integrity.

Please note that because of the nature of this product, the lead time is typically 2-3 days but may be up to one week. We will make every effort to ship your order as soon as possible.

The PureAire Chlorine Dioxide Gas Detector is a fixed, compact gas monitor that’s ideal for protecting workers from toxic and corrosive gas exposure in the workplace. It consists of a transmitter/controller connected to a dedicated, renewable gas sensor that automatically inputs the gas and measurement range. Designed as a stand-alone monitor, the Chlorine Dioxide Gas Detector can also be connected to any programmable logic controller or SCADA system. PureAire also manufactures toxic gas detectors with a remote sensor.

The heart of the Chlorine Dioxide Gas Detector is the smart, renewable chlorine dioxide sensor cell programmed with gas and measurement range information. When servicing the sensors, they can be recharged with fresh electrolyte and dynamically gas-calibrated in the maintenance shop away from the transmitter.

High Performance, Low Annual Cost

PureAire’s Chlorine Dioxide Gas Detector — the industry leader in low-maintenance gas detection. Our innovative renewable sensor technology allows you to recharge sensors right in the field, eliminating the need for costly replacements. At just 20% of the cost of traditional disposable sensors, and with routine maintenance materials averaging only $70/year, this detector offers significant savings, year after year.

Plug-and-Play Stand-Alone Monitoring

Get up and running in minutes. The Chlorine Dioxide Gas Detector is built for stand-alone, hassle-free operation — simply mount it near the target area, plug it into any 115VAC or 220VAC outlet, and you’re actively monitoring.

Equipped with a built-in horn and LED alarm indicators, this detector ensures your personnel receive immediate warnings in the event of a hazardous gas leak. The system also features dedicated alarm and fault relays for integration with remote alarms or control systems, plus a 4- 20mA analog output that provides real-time data to PLC and SCADA systems.

24/7 Smart Monitoring with Built-In Diagnostics

Unlike basic detectors, PureAire’s Chlorine Dioxide Gas Detector features smart, continuously supervised electronics that monitor system performance around the clock. If a fault occurs, the detector’s analog output and fault relay will automatically notify control room personnel, providing instant alerts and peace of mind.

Maintenance is simple. A dedicated microcontroller in the sensor allows you to remove it from the transmitter for calibration and maintenance. Once calibration data is entered into the sensor, it’s instantly transferred to the transmitter when reconnected, saving you time and ensuring accuracy.
