Product Introduction：

The monitoring instrument complies with the national standard "HJ609-2019 Technical Requirements and Testing Methods for Hexavalent Chromium Water Quality Automatic Online Monitoring Instrument", and can work continuously for a long time without human supervision 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：

This product is determined using the diphenylcarbazide photoelectric colorimetric method. After mixing the water sample with a regulator, hexavalent chromium reacts with the indicator in an acidic environment to form a colored complex. The monitor detects the change in color and converts this change into a hexavalent chromium value output.
