7SO2-5 7SO2-20 Electrochemical Sulfur Dioxide Sensors For Environmental Monitoring

• Uses:
  • Environmental Monitoring: Sulfur dioxide is one of the important indicators of air quality, and the 7SO2 - 5 gas sensor can be used to monitor the sulfur dioxide concentration in the atmosphere. It provides timely and accurate data support for environmental protection departments, helping them evaluate air quality and take corresponding environmental protection measures.
  • Industrial Safety: In industrial production processes, such as coal - fired power plants, smelting plants, and chemical plants, a large amount of sulfur dioxide may be produced during production. The sensor can be used to detect the sulfur dioxide concentration in the factory environment in real - time, timely alarm for excessive concentrations, and protect the health of workers and the normal operation of equipment.
  • Food and Beverage Processing: Sulfur dioxide is often used in food and beverage preservation. The 7SO2 - 5 sensor can be used to detect the sulfur dioxide content in food and beverages, ensuring that it is maintained at an appropriate concentration to keep the taste and aroma of the product, while also ensuring food safety.
• Features:
  • High - sensitivity Detection: It has a sensitivity of 0.5 ± 0.1 μA/ppm, and the resolution can reach 0.08 ppm2. It can accurately detect low - concentration sulfur dioxide gas, meeting the needs of different application scenarios for precise measurement.
  • Fast Response: The response time (T90) is ≤ 70 s, which can quickly detect the change of sulfur dioxide concentration, and can quickly respond to the sudden increase or decrease of sulfur dioxide concentration in the environment, providing timely monitoring data.
  • Good Stability: The zero signal is < ±0.2 μA, and the long - term output drift is < 2% signal/month. It can maintain relatively stable performance in different environmental conditions, with little influence from factors such as temperature and humidity, reducing the frequency of calibration and maintenance.
  • Strong Environmental Adaptability: Its working temperature range is -20℃ ~ 50℃, the pressure range is 1 ± 0.1 atm, and the humidity range is 15% ~ 90% rh (non - condensing), which can work normally in a variety of complex environmental conditions.
  • Long Service Life: In clean air, the expected operating life can reach 2 years, which can reduce the replacement cost and maintenance workload, and is suitable for long - term continuous monitoring applications.
