ME3-H2

ME3-H2 Electrochemical Hydrogen Gas Sensor - Detection Gas: Hydrogen Gas Sensor, H2 sensor - Detection Range: 0~1000ppm H2 - Application: H2 industrial and environmental protectionl fields Principle Introduction: Winsen Electronics, as a professional gas sensor manufacturer, produce hydrogen sensor, industrial H2 sensor, using fuel cell/ electrochemical working principle. ME3-H2 electrochemical sensor detect gas concentration by measuring current based on the electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the working electrode inside the electrolytic cell, the current produced in electrochemical reaction of the target gas are in direct proportion with its concentration while following Faraday law, then concentration of the gas could be get by measuring value of current. Applications : Widely used in industrial and environmental protectionl fields Technical parameters : Detection gas H2 Measurement Range 0~1000ppm Max detecting concentration2000ppm Sensitivity (0.010±0.005) µA/ppm Resolution ratio 2ppm Response time (T90) 90S Bias voltage 0mV Load resistance (recommend)10Ω Repeatability <2%output value Stability (/month) <2% Output Linearity linear Zero drift (-20+40C) 20ppm Storage temperature -20+50C Storage Humidity 15%~90%RH Pressure range (kPa) 90-110 Anticipated using life 2 years
