Description

MEu-NH3 Ammonia Gas Sensor Three Electrode Electrochemistry Potentiostatic Electrolytic Type

Core Operating Principle
Utilizes a three-electrode system (Working Electrode [WE], Reference Electrode [RE], and Counter Electrode [CE]):
Ammonia gas permeates a gas-permeable membrane into the electrolyte chamber, where it undergoes an electrochemical oxidation reaction at a fixed potential, releasing electrons to generate a minute current. The magnitude of the current is strictly linearly proportional to the ammonia concentration; the downstream circuitry captures this current and converts it into an ammonia concentration value in ppm.

Typical Application Scenarios
Industrial Safety: Ammonia leak alarms for cold storage refrigeration rooms, fertilizer plants, pharmaceutical workshops, and chemical processing facilities;
Environmental Monitoring: Online monitoring of exhaust emissions at wastewater treatment plants and landfill sites;
Livestock Farming: Ammonia concentration monitoring in pig farms and poultry houses, integrated with ventilation systems;
Municipal Environment: Ammonia detection for odor control in public restrooms and waste transfer stations.
