ME4-NH3 Ammonia Gas Sensor

Ammonia Gas Sensor

Applications :

*For ammonia gas detection in industrial occasions and environmental protection field.

Product Advantages:
  • *Low power consumption
  • *High precision, high sensitivity
  • *Wide linear range
  • *Good anti-interference ability
  • *Excellent repeatability and stability
Product Description:

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.
