Product Introduction：

The monitoring device complies with the national standard "GB 7466-87 Determination of Total Chromium in Water Quality", and can work continuously without human supervision for a long time according to on-site settings. It is suitable for monitoring water quality such as pollution source discharge wastewater, municipal sewage treatment plant wastewater, and surface water.

Product Principle：

Chromium in the water sample is oxidized to hexavalent chromium by an oxidant, and reacts with the indicator in an acidic environment to form a colored complex. The monitor detects the change in color and converts it into chromium value output.
