Chlorine Dioxide (ClO₂) Sensor
Real-Time Chlorine Dioxide Monitoring Sensor for Safer Environments
Chlorine Dioxide (ClO₂) is a yellow-green gas known for its strong oxidizing properties. It is widely used in water treatment, pulp bleaching, and disinfection processes. However, at even low concentrations, ClO₂ can be harmful to human health and corrosive to materials. Accurate monitoring is essential for worker safety, equipment protection, and regulatory compliance. Oizom’s Chlorine Dioxide sensor provides real-time and precise measurement, even at trace levels. Designed for industrial use, it ensures long-term performance across demanding conditions and integrates easily into Oizom’s fixed and mobile air quality monitoring systems.
Oizom’s ClO₂ sensor operates on electrochemical sensing technology, where Chlorine Dioxide molecules react at the electrode surface, producing a microcurrent. This current is directly proportional to the ClO₂ concentration in the air. With a detection range of 0–1 ppm and a response time of 2-5 minutes, the sensor is ideal for critical environments where fast detection and high sensitivity are required. Its linearity and resolution make it suitable for real-time emission tracking and workplace exposure monitoring.
Built on the OGS (Oizom Gas Sensor) architecture, the ClO₂ sensor is engineered for durability, accuracy, and minimal drift. The sensor offers linear output up to 1 ppm and maintains stability across a wide temperature and humidity range. With its compact and robust housing, the sensor withstands harsh industrial environments and ensures long-term performance with minimal maintenance. It integrates seamlessly into our monitoring solutions, making it suitable for both fixed and mobile monitors, including confined spaces and open processing units.
The OGS design emphasizes selectivity, reducing cross-sensitivity, which helps ensure more reliable ClO₂ data. This makes the sensor reliable for continuous monitoring in various sectors.
The Oizom ClO₂ sensor is calibrated with various methods to ensure reliable baseline performance. For ongoing accuracy, the sensor is calibrated using certified ClO₂ calibration gas. This helps correct environmental drift and adapt to site-specific conditions.
The sensor also goes through colocation calibration, where it is deployed alongside a high-accuracy reference analyzer to fine-tune readings under real-world conditions. These calibration processes ensure the sensor delivers consistent and precise data throughout its lifespan, especially in high-exposure or dynamic environments.
