DR-2080 coliform online analyzer Introduction
The fecal coliform grows in a 44.5 °C environment and can be fermented by lactose to produce acid to produce gas and produce β-D-galactosidase (E.C. 3.2.1.23). β-D-galactosidase hydrolyzes different substrates to form colored substances, which are continuously photometrically determined by light of a specific wavelength. The concentration of coliforms can be obtained by the color ratio proportional to the number of coliforms in the water. 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;
