Overview

The nitrate nitrogen analyzer can be directly connected through a digital communication interface. The NO3-N analyzer provides simple, reliable, and cost-effective on-site sensor monitoring data, and has remote status display, calibration, setting, and fault diagnosis functions. The nitrate nitrogen analyzer can be directly installed in water quality analysis instruments for applications such as reservoirs, rivers, tap water, and sewage, using an IP68 rated dust-proof and waterproof sturdy housing, a 1500N high-strength Kevlar cable, and a transmission distance of up to 1.2 kilometers.

measuring principle
Using ion selective electrode method, a thin film on the probe head is used to allow only specific ions to penetrate, generating electrophoretic effect and electrochemical potential. According to the Nernst equation, the potential difference is converted into the concentration of the measured substance. Combine nitrate nitrogen and chloride ion selective electrodes, reference electrodes, and temperature sensors to form a column, and mutually correct and compensate for interference.

Installation method
Immersive, flowing, and plug-in
