Product Introduction:
The composite ammonia nitrogen sensor uses an ion-selective electrode detection method. The sensing part consists of a pH electrode, temperature sensor, and potassium ion electrode, forming a composite electrode. Other electrodes compensate for ammonia nitrogen measurements, improving accuracy. The composite ammonia nitrogen sensor is widely used for online water quality monitoring in surface water, groundwater, municipal wastewater, and pollution sources.
Product Features:
Composite electrode design helps eliminate the influence of interfering ions.
No sample pretreatment required, suitable for online monitoring.
New ion sensor membrane head design for longer service life.
Easy maintenance with a modular electrode design for simple operation.
Optional cleaning device to reduce maintenance workload.
Good reproducibility and long-term stable operation.
