Overview

The UV-4000 multi parameter UV absorption water quality analyzer is a professional online water quality analysis tool that utilizes UV spectroscopy technology to achieve real-time, reagent free, and multi parameter monitoring. It is particularly suitable for situations that require high-frequency monitoring of organic matter and nitrate changes, and is one of the core sensors in smart water management and water environment warning systems.

Product Details

The UV-4000 multi parameter ultraviolet absorption water quality analyzer is an optical analysis instrument that uses ultraviolet spectroscopy technology. It is based on the characteristic absorption principle of substances towards specific wavelengths of ultraviolet light. By scanning the full spectrum of the 200-800nm band, multiple parameters in water can be measured in real-time and continuously without the need for chemical reagents.

This instrument is mainly used to simultaneously monitor key indicators such as COD, nitrate nitrogen, TOC, and turbidity. It adopts an immersion probe design, which has the characteristics of fast response, no secondary pollution, and low maintenance. It is widely used in online monitoring and early warning of drinking water sources, surface water, and sewage treatment plants.

The UV-4000 multi parameter UV absorption water quality analyzer is a high-quality, high stability, high-precision, and low maintenance instrument. Using UV visible spectroscopy, combined with a pressure sampling system, makes the measurement faster, more stable, and reliable. The special flow pool design solves the blockage caused by large solid particles passing through; The turbidity was compensated for using a dual wavelength measurement method. The UV light source uses imported high-quality xenon lamps with a long service life. Adopting modular design, electrical chemistry parameters such as pH, ORP, dissolved oxygen, and conductivity probes can be selected according to actual needs.

Purpose:

Water plants, sewage treatment plants, rivers, reservoirs, seawater, inlet and outlet for water quality testing.

Key Features:

1. Low maintenance, high reliability

For measurement, our design philosophy places particular emphasis on low maintenance and high reliability. The instrument is equipped with an internal automatic cleaning system, which injects 5% dilute sulfuric acid during the cleaning process. It is usually cleaned once a day. During the cleaning process, in order to avoid zero drift caused by long-term operation of the instrument, the instrument will automatically zero.

2. User friendly interface

The color touch screen interface is more intuitive, concise, and convenient for instrument testing and setup. The selection interface for multiple languages is easier to operate. Different interfaces provide various quick testing and diagnostic functions for different parameters.

3. Modular design functionality

Modular design, where each parameter corresponds to a module. Users can customize the required modules according to different applications.
