Product Description: ME4-SO2 Electrochemical Sulfur Dioxide Gas Sensor For Sulfur Dioxide Detection In Industry And Environmental Protection
Features: ME4-SO2 type sensor is a constant potential electrolysis type SO2 sensor. SO2 and O2 undergo corresponding REDOX reaction at the working electrode and the opposite electrode and release charge to form current, the current is proportional to the concentration of SO2, and the concentration of SO2 can be determined by testing the current size. Item parameter Detection gas Sulfur dioxide (SO2) Measuring range 0-20ppm z Maximum measurement limit 200ppm Sensitivity (0.8±0.2) uA/ppm Resolution 0.1ppm Response time (T90) ≤30s Bias voltage 0mV Load resistance (recommended) 10Ω Repeatability < 2% output value Stability (/ month) < 2% The output linearity is linear Zero drift (-20℃-40℃) ≤0.2ppm Temperature range -20℃-50℃ Humidity range 15%-90%RH Pressure range standard atmospheric pressure ±10% Detection life 2 years (in the air)
