Dimension (Unit: mm)

Ammonium nitrogen sensor size

Note: The sensor connector is a male M16-5 pole waterproof connector.

Installation Method

Ammonium nitrogen sensor installation method

Note: The sensor should not be installed upside down or horizontally, but at least at an angle of 15 degrees or more. The interface of sidewall mounting must be beveled at 15 degrees, otherwise it will affect the normal testing and use of the electrodes.

Application

Tips: What is the working principle of the sensor?

The working principle of the Ammonium Nitrogen Sensor is based on the ion-selective electrode method, which detects ammonium ions (NH₄⁺) in water. The sensor measures the electrical potential difference created by ammonium ions interacting with the ion-selective membrane, converting this into a corresponding concentration value. This method ensures high sensitivity, accuracy, and stability, making it ideal for monitoring ammonium nitrogen levels in various water quality applications.
