Product Description

Product Overview

The ammonia‑nitrogen sensor is a fast‑response device for measuring ammonia‑nitrogen concentrations, based on ion‑selective electrode technology. It employs imported U.S.-made sensors for ammonium, potassium, and pH, ensuring stable and accurate performance. Equipped with advanced measurement and compensation algorithms, the sensor supports automatic potassium‑ion and pH compensation. Its state‑of‑the‑art matrix calibration delivers highly precise calibration results. The sensor features in‑situ measurement, no need for reagents, rapid response, no pre‑treatment required, low power consumption, and minimal maintenance. It is widely applicable to wastewater process control and surface‑water monitoring (including micro‑water stations and buoys).

Product Features

It features automatic compensation for pH, potassium ion concentration, and temperature. When a single sensor fails, the potassium ion concentration and pH value can be manually set, allowing the sensor to continue operating.

It employs imported American sensors for chloride, potassium, and pH, ensuring stable and accurate measurements. Each sensor can be replaced independently, offering simple operation and minimal maintenance.

In-situ measurement, reagent-free, rapid response, no pre‑treatment required, low power consumption, and minimal maintenance. Fast response time enables immediate feedback on water quality.

A fast‑response temperature sensor promptly measures water‑sample temperature and simultaneously provides temperature compensation to all connected sensors. Its compact design and corrosion‑resistant housing ensure reliable long‑term operation underwater.

Due to the mutual interference between root ions and potassium ions, the unique matrix‑calibration design enables calibration even under complex interfering conditions.
