UE-NH3 long-acting ammonia sensor is a constant potential electrolytic electrochemical sensor. Ammonia undergoes an oxidation-reduction reaction inside the sensor and releases electric charges to form a current. The concentration of ammonia can be determined by measuring the magnitude of the current.

Application

Widely used to detect and monitor ammonia NH3 gas (odor gas) in animal husbandry, industry, and environmental protection etc.

Features

Low consumption
High precision
High sensitivity
Wide linear range
Good anti-interference ability
Excellent repeatability and stability
