Overview

The GR Antilines Aniline Water Quality Online Automatic Monitor uses the N - (1-naphthyl) ethylenediamine hydrochloride method to measure the concentration of aniline in water. The monitor adopts an integrated design, which can quickly complete sampling and testing work, and has the characteristics of automation, intelligence, stable performance, accuracy and reliability. This monitor is suitable for water quality monitoring in industrial wastewater, domestic sewage, surface water, groundwater, and drinking water fields.

Product Details

The GR Antilines Aniline Water Quality Online Automatic Monitoring Instrument consists of a sampling system, a metering system, a digestion system, a detection system, and a programmable control system. Collect water samples through an automatic sampling system, and after passing through a high-precision photoelectric sensing measurement system Aniline compounds diazotize with nitrite under acidic conditions, and then couple with N - (1-naphthyl) ethylenediamine hydrochloride to generate a purple red dye. The absorbance of the dye is measured at a specific wavelength to convert the concentration of aniline compounds in the sample solution.

Can achieve the functions of standard sample verification and spiked recovery;

Capable of remote transmission control, bidirectional communication, and other functions;

Total amount of liquid for a single sample<>

Equipped with automatic protection and cleaning functions for power and water outages;

Equipped with measurement over limit alarm function, supporting remote setting of over limit values;

Adopting high-resolution color touch screen, easy to operate and rich in information;

Integrated digestion/colorimetric module patented technology, complete digestion, compact structure, high efficiency;

High precision infrared visible photoelectric non-contact measurement system, with high measurement accuracy and high operational reliability;

By conducting two colorimetric measurements on the same sample within one analysis cycle, the sample concentration can be calculated, effectively compensating for the interference caused by sample chromaticity and turbidity;

Through independently designed sampling pipelines, sampling, quantification, liquid discharge, and each reagent have independent pipelines to avoid measurement errors caused by contamination.
