Product Introduction
I.Ammonia Gas Sensor (NH3 Sensor) ME4-NH3 Product Description
The ME4-NH3 sensor is a constant potential electrolyticNH3 sensor. NH3 undergoes a series of redox reactions inside the sensor and releases charge to form a current. The magnitude of the current is proportional to the NH3 concentration. By measuring the current, the NH3 concentration can be determined.
II. Ammonia Gas Sensor (NH3 Sensor) ME4-NH3 Features
Low power consumption, high precision, high sensitivity, wide linear range, strong anti-interference capability, excellent repeatability and stability
III. Ammonia Gas Sensor (NH3 Sensor) ME4-NH3 Main Applications
Widely suitable for ammonia detection in industry and environmental protection.
