DR-2020 multi-parameter heavy metal online analyzer Introduction
Using the principle of anodic stripping voltammetry (ASV) approved by international authoritative institutions, the analytical solution is first pre-electrolyzed under certain conditions to concentrate the component to be measured on the working electrode, and then the solution is allowed to stand still for a period of time, and then the anti-application is applied. The test object enriched in the working electrode is eluted with a voltage, and the concentration of the heavy metal to be tested is determined by the elution voltammetry curve. Features
With a 10.4 inch large touch screen, you can use the instrument without professional training;
The instrument has a small reaction system and supports the separation of waste water and waste liquid.
Small size for easy transportation and installation;
Customized solutions can be provided to reduce user operation and maintenance costs according to water conditions;
Daily maintenance can be completed in 5 minutes;
WeChat applet "Water Quality Cloud" supports remote diagnosis and remote operation and maintenance, WeChat scans two-dimensional code report faults, and the after-sales service is more accurate and faster;
