ME3-NH3

ME3-NH3 Electrochemical Ammonia Sensor - Detection Range: NH3, ammonia gas sensor - Detection Range: 0~50ppm NH3 - Application: industrial and environmental protectionl fields ME3-NH3 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 NH3, ammonia gas sensor Measurement Range 0~50ppm Max detecting concentration 200ppm Sensitivity (0.10±0.05)µA/ppm Resolution ratio 0.5ppm Response time (T90) ≤90S Bias voltage 0mV Load resistance (recommend) 10Ω Repeatability <10%output value Stability (/month) <10% Output Linearity linear Zero drift (-20-40C) -3-10ppm Storage temperature -20-50C Storage Humidity 15%~90%RH Pressure range (kPa) 90-110 Anticipated using life 2 years
