Product Overview

The WDet-7000TPN Total Nitrogen Water Quality Online Analyzer is a newly developed online total nitrogen monitoring instrument based on a brand-new metering technology platform, combined with independently developed integrated digestion and spectral measurement technology.

The working principle of this product complies with the "HJ 636—2012 Water Quality — Determination of Total Nitrogen — Alkaline Potassium Persulfate Digestion UV Spectrophotometric Method," featuring high reliability, a low limit of quantification, and good stability. This product has passed CCEP certification.

Product Features

Adopts high-temperature and high-pressure digestion technology, equipped with comprehensive protection and self-check functions to ensure efficient reactions and the safety of equipment and personnel.
The brand-new quantification method offers strong anti-interference capability; the integrated valve island design ensures high precision, and it supports automatic calibration and multi-range switching.
Equipped with fault self-diagnosis, leakage alarm, and automatic locking functions; operating status is recorded in real time for convenient maintenance.
Features a 7-inch Android touchscreen with smooth and intuitive operation, allowing flexible parameter settings and a user-friendly experience.
Rich interfaces support remote upgrades and monitoring, facilitating function expansion and remote operation and maintenance.
