WQA-3100 Automatic Water Quality (Sulfide) Analyzer

Product Overview

The WQA-3100 water quality (sulfide) automatic analyzer is a new type of fully automatic online analyzer used for measuring sulfides in water. This product is based on a distillation platform, a magnetic conductivity measurement platform, and combined with constant temperature optical fiber technology to achieve high-precision, low detection limit, high stability, and low maintenance sulfide fully automatic online monitoring. The working principle of this product complies with the "HJ 824-2017 Determination of Sulfides in Water Quality - Methylene Blue spectrophotometric method", and it has the characteristics of high reliability, low lower limit of quantification, and good stability. It is widely used in groundwater, surface water, domestic sewage, industrial wastewater and other fields.

Product Features

Magnetic permeability measurement technology is not affected by high chromaticity and suspended solids
Special flow path design allows for flexible control of the analysis backboard and distillation backboard for operation
Equipped with a high-performance and high-efficiency online distillation device, the water sample is distilled to produce hydrogen sulfide gas for measurement, eliminating the interference of turbidity and chromaticity, thus ensuring accurate measurement of sulfides
After pre distillation of the sample, it can be automatically adjusted to a fixed volume for more accurate measurement
Single channel highly integrated valve island, easy and fast maintenance, disassembly, and cleaning
Upgrading software and exporting data using a USB flash drive is more convenient and efficient
Adopting a 7-inch high-definition color display screen touch control based on the Android operating system, modular design, and a back panel that can work off the screen, it is not easily affected by erroneous operations
Built in verification module with zero core and cross core functions
● Reverse control function, which can automatically start the instrument for sampling through flow rate, pH and other methods
● Store 10 years of data and support 2 different protocol uploads simultaneously
