1 PC ME4-NH3 Ammonia Gas Sensor

ME4-NH3 ammonia gas sensor is constant potential electrolysis type. Oxidation-reduction reaction with ammonia gas take place inside of the sensor. The process releases electric charge and generates current. The current is in direct proportion to the concentration of ammonia gas. So the concentration of the target gas could be got by measuring the value of current. Application For ammonia gas detection in industrial occasions and environmental protection field. Features Low power consumption High precision High sensitivity Wide linear range Good anti-interference ability Excellent repeatability and stability Specifications Detection gas Ammonia gas (NH3) Detection range 0～50ppm Max range 200ppm Sensitivity (0.12±0.03) µA/ppm Resolution 0.1ppm Response time (T90) ≤90S Bias voltage 0mV Load resistance 10Ω (recommended) Repeatability ＜10% Output value Stability (/month) ＜10% Output linearity Linear Zero drift (-20℃～40℃) -3～10ppm Temperature range -20℃～50℃ Hu
