Product Overview

The WDet-7000 Online Ammonia Nitrogen Water Quality Analyzer is based on our company's newly developed integrated digestion and colorimetric technologies, enabling fully automated online monitoring of ammonia nitrogen with fast analysis speed, high precision, low detection limit, and low failure rate. The working principle of this product complies with "HJ 536-2009 Water Quality - Determination of Ammonia Nitrogen - Salicylic Acid Spectrophotometric Method." It has passed CCEP certification.

Product Features

The newly developed metering technology is immune to interference from high chromaticity, excessive suspended solids, and numerous bubbles, featuring fast metering speed and high precision.
High detection precision, low lower limit of quantification, and minimal long-term drift of the instrument.
Strong resistance to interference from chromaticity and calcium/magnesium ions.
Equipped with self-diagnostic function.
Single-channel highly integrated valve manifold, allowing individual valve maintenance, disassembly, and cleaning.
Equipped with alarm function, quality control function, and reverse control function.
Expandable all-weather networking capability for monitoring instrument operating status anytime and anywhere.

Application Fields

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