SO2/CF-2000 Three-electrode Electrochemical Sulfur Dioxide (SO2) Gas Sensor for Industrial Process Gas Monitoring
Product Features:
Built-in Professional Anti-interference Filter: Equipped with customized internal filter structure, which effectively filters interfering gases such as hydrogen sulfide and hydrogen chloride in flue gas environments. It significantly reduces false alarms and detection deviation, ensuring pure and accurate SO2 measurement signals in complex mixed gas conditions.
Wide-range High-concentration Detection: Supports 0-2000 ppm full-scale sulfur dioxide monitoring, suitable for industrial high-emission concentration scenarios that conventional low-range sensors cannot adapt to, covering most industrial flue gas and combustion emission detection requirements.
Zero-bias Simple Circuit Design: Operates at 0V zero-bias voltage without complex peripheral driving circuits. It features simple matching, low development difficulty and plug-and-play replacement capability, greatly simplifying instrument hardware design.
Fast Dynamic Response Speed: Optimized internal gas diffusion structure shortens gas reaction time, with T90 response time less than 30 seconds. It can quickly track sudden changes in SO2 concentration to support real-time emission monitoring and early warning.
Ultra-low Baseline Drift Performance: Strict industrial production process controls zero current drift effectively. The baseline range is maintained within -2 ppm to +2 ppm in pure air at 20°C, ensuring long-term stable detection accuracy and reducing calibration frequency.
Excellent Environmental Adaptability: Adapts to wide temperature and humidity fluctuation ranges, maintaining stable working performance in high-humidity and variable industrial environments. It features strong environmental tolerance for on-site flue gas monitoring scenarios.
Industrial-grade Durability: Adopts anti-aging electrolyte and high-stability electrode materials, with a typical service life of up to 24 months in normal atmospheric environments, meeting long-term continuous online monitoring demands.
Product Applications:
The SO2/CF-2000 high-range anti-interference sulfur dioxide sensor is widely used in industrial flue gas emission supervision, atmospheric environmental protection monitoring and industrial safety detection fields:
Industrial Flue Gas Emission Monitoring: Applied in thermal power plants, chemical plants, metallurgical factories, waste incineration plants and boiler flue gas detection systems for real-time monitoring of high-concentration SO2 emissions, supporting environmental compliance supervision.
Atmospheric Environmental Quality Monitoring: Integrated into urban ambient air quality monitoring stations and industrial park environmental monitoring terminals to track sulfur dioxide pollutant concentration changes and assist pollution data statistics and early warning.
Combustion Equipment Safety Detection: Used for gas monitoring of industrial combustion equipment, fuel equipment and exhaust pipelines to evaluate combustion sufficiency and harmful gas emission levels.
Portable Industrial Detection Instruments: Serves as the core sensing unit of portable flue gas analyzers and industrial gas detectors for on-site inspection, environmental law enforcement and emission spot-check work.
Industrial Process Gas Monitoring: Deployed in chemical production, sulfur-related industrial reaction and exhaust treatment processes to monitor real-time SO2 concentration and ensure safe and compliant production operations.
Environmental Scientific Research & Experiment: Applied in laboratory environmental simulation experiments and industrial flue gas testing platforms to provide accurate and stable high-range SO2 detection data support.
