Technical features
♦ Easy to operate, suitable for unmanned online continuous monitoring, and can remotely upload detection data results.
♦ The volume of water sample collected for testing reaches 100mL, which can achieve low detection of 1/100mL.
♦ The relative error of comparison with laboratory methods should be less than 35%.
♦ On site testing output results to solve the problem of microbial characteristics easily changing during water sample collection and transportation, ensuring the accuracy of data results.
♦ According to the characteristics of the actual water sample being tested, a portable calibration module (based on national standard methods) can be used for on-site calibration. Reduce due to experiments
Indoor bacteria
Detection errors caused by differences in strains and strains in the environment.
♦ Built in turbidity correction function can reduce the impact of increased turbidity during microbial cultivation on detection results.
♦ The concentration range of the test water sample is wide to avoid the occurrence of fully positive results.
♦ Automatic pipeline disinfection and cleaning to eliminate cross interference of water samples.
♦ Equipped with a microcomputer communication structure, it has networking functions with the manufacturer's DCS and local environmental government departments.
