ME3-SO2 sulfur dioxide sensor Introduction: ME3-SO2 electrochemical gas sensor is based on the electrochemical principle, which uses the measured gas to generate corresponding Redox on the working electrode and the counter electrode of the sensor and release charges, and forms a current through the external circuit. The current is proportional to the gas concentration, so as to realize the quantitative measurement of target gas. Widely suitable for SO2 detection in industry and environmental protection Features: 1. Low power consumption, high accuracy, and high sensitivity 2. Wide linear range and strong anti-interference ability 3. Excellent repeatability and stability Technical parameters: Detection gas: sulfur dioxide (SO2) Detection range: 0-20ppm Maximum measurement limit: 150ppm Sensitivity: (0.6 ± 0.2) µ A/ppm Resolution: 0.1ppm Response time (T90): ≤ 30S Bias voltage: 0mV Load resistance (recommended): 10 Ω Repeatability:<2% of output value Stability (per month): ＜ 2% Output linearity: linear Zero drift (-20 ℃~40 ℃): ≤ 0.2ppm Temperature range: -20 ℃~50 ℃ Humidity range: 15%~90% RH Pressure range: standard atmospheric pressure ± 10% Service life: 2 years (in air)
