Benchtop multi-parameter drinking water analyzer

The contents of project

1、Product introduction of benchtop multi-parameter drinking water analyzer：

Benchtop multi-parameter drinking water analyzer ERUN-ST-MU97 can be selected according to user needs. It is designed with reference to the "GB 5749-2022 Hygiene Standard for Drinking Water" and can detect toxicological indicators including arsenic, lead, hexavalent chromium, cyanide, etc.; color, turbidity, Sensory properties and general chemical indicators such as PH, iron, copper, manganese, and CODMn; conventional indicators and requirements for disinfectants such as residual chlorine, total chlorine, and chlorine dioxide are widely used in the testing of routine items in tap water and drinking water.
