Product Overview

The WDet-7000TPN Online Nitrate Nitrogen Water Quality Analyzer is a newly developed online nitrate nitrogen monitoring instrument based on our company's patented new metering technology platform, combined with self-developed integrated spectral measurement technology. The working principle of this product complies with "HJ/T346—2007 Water Quality—Determination of Nitrate Nitrogen—Ultraviolet Spectrophotometry," featuring high reliability, low limit of quantification, and excellent stability.

Product Features

Adopts a novel quantification technology resistant to color and turbidity interference; integrated valve island reduces dead volume, easy to disassemble and clean, with low-cost maintenance.
Built-in multi-range adaptive adjustment; fully automatic calibration and cleaning without manual intervention.
Equipped with self-diagnosis and safety protection functions; real-time leak alarm and lockout; complete fault information recording for easy query.
Supports remote monitoring, upgrade, and maintenance via ETHERNET/GPRS and other interfaces.
Features a 7-inch Android touchscreen with intuitive interface and smooth operation.
Provides multiple industrial communication and control interfaces, with flexible function expansion as needed.

Application Fields

Suitable for pollution sources, industrial process water, municipal wastewater, and other fields.
