Winsen ME3-H2S Hydrogen Sulfide Sensor - Electrochemical Gas Sensor
The Winsen ME3-H2S is an electrochemical hydrogen sulfide gas sensor designed for industrial and environmental monitoring. It provides a 0-100 ppm measurement range with high sensitivity and linear output, compatible with standard gas detection systems requiring a 10Ω load.
Features
- Electrochemical sensing principle for H2S gas detection
- Measurement range of 0 to 100 ppm with 0.1 ppm resolution
- High sensitivity of (0.8±0.15) µA/ppm
- Fast response time of less than 30 seconds (T90)
- Excellent long-term stability with less than 2% drift per month

The ME3-H2S sensor operates on a fuel cell/electrochemical principle, generating a current proportional to the concentration of hydrogen sulfide gas via oxidation at the working electrode. This Faraday-law-based process ensures a direct, linear relationship between gas concentration and output signal.
Engineered for reliability in demanding environments, the sensor features minimal zero drift across a -20°C to 40°C operating range and maintains stability within 2% of output value per month. Its robust design supports operation at 90-110 kPa pressure and storage in conditions from -20°C to 50°C and 15-90% RH.
