DS4-O3-100 Intelligent Electrochemical Ozone Sensor

1. Product Overview​​:

The ​​DS4-O3​​ is a high-performance gas sensor specifically designed to detect ​​ozone (O₃)​​ concentrations. Utilizing advanced electrochemical sensing technology, it delivers high sensitivity, rapid response, and excellent selectivity, making it ideal for industrial safety, environmental monitoring, and medical equipment applications.

​​2. Key Features​​:

• ​​Target Gas​​: Ozone (O₃), optimized for precise detection in environmental or industrial processes.
• ​​Detection Principle​​: ​​Electrochemical sensing​​. Ozone undergoes redox reactions on the electrode surface, generating a current signal proportional to its concentration—combining high accuracy with low power consumption.
• ​​Measurement Range​​: ​​0–1 ppm​​ (standard); customizable up to ​​0–5 ppm​​ or higher (specify model).
• ​​Sensitivity​​: Detects ozone concentrations as low as ​​0.01 ppm​​ (exact value subject to testing).
• ​​Response Time (T90)​​: ≤ ​​30 seconds​​ (time from gas exposure to stable output).
• ​​Recovery Time​​: ≤ ​​60 seconds​​ (time to return to baseline after gas removal).

3. Working Principle​​:

The DS4-O3 employs a ​​three-electrode electrochemical cell​​, comprising:

• ​​Working Electrode (WE)​​: Ozone diffuses through a permeable membrane and undergoes oxidation, releasing electrons to generate a current.
• ​​Counter Electrode (CE)​​: Completes the redox reaction to maintain circuit balance.
• ​​Reference Electrode (RE)​​: Provides a stable potential reference.

The current magnitude is directly proportional to the ozone concentration, enabling precise quantification.

​​4. Typical Applications​​:

• ​​Industrial Safety​​:
  • Leak detection in ozone generators/disinfection systems (e.g., water treatment, food processing).
  • Safety monitoring in semiconductor manufacturing and laboratories.
• ​​Environmental Monitoring​​:
  • Outdoor air quality stations for ozone pollution tracking (complies with environmental standards).
  • Indoor ozone emission monitoring in air purifiers (e.g., negative ionizers, UV photolysis devices).
• ​​Medical & Scientific Research​​:
  • Calibration of medical ozone therapy devices.
  • Laboratory experiments involving ozone generation/decomposition.

​​5. Usage Guidelines​​:

• ​​Calibration​​:
  • Required every ​​6 months​​ (or per usage frequency); use certified ozone gas (e.g., 0.1 ppm or 0.5 ppm) for standardization.
  • Calibrate in stable temperature/humidity conditions to avoid environmental interference.
• ​​Cross-Sensitivity​​:
  • May respond slightly to other oxidizing gases (e.g., Cl₂, NO₂); implement algorithms or multi-sensor fusion to mitigate interference.
• ​​Environmental Adaptation​​:
  • Avoid high temperatures, humidity, or corrosive environments (e.g., acid/base fumes); prolonged exposure may reduce lifespan or accuracy.
  • In dusty environments, install a dust filter to prevent membrane clogging.
• ​​Storage​​:
  • Unused sensors should be stored in a dry, cool place (0–25°C, <60% RH) to prevent "poisoning" from prolonged ozone exposure.
