Instrument Introduction

The economical total chromium analyzer is designed and developed based on the improved standard GB7466-87 "Determination of Total Chromium in Water Quality". The detection system uses imported optical components, which have stable and reliable performance. Adopting a 5-inch LCD display screen, the interface is simple and easy to understand, coupled with a simple three-step detection program, users can use it quickly and accurately.

Detection Principle

The YC-205S economical total chromium analyzer is designed and developed based on the improved standard GB7466-87 "Determination of Total Chromium in Water Quality". It adds an oxidant to convert trivalent chromium into hexavalent chromium, and then reacts with hexavalent chromium to form a purple red complex. Its absorbance is measured by spectrophotometry, and the value of total chromium in water (mg/L) is directly displayed after calculation by the instrument chip.
