The YC105B portable COD analyzer uses a low range to measure the total absorbance of unreduced Cr6+and reduced Cr3+at specific wavelengths. Measure the absorbance of Cr3+produced by reduction at a certain wavelength under high range, and directly display the COD content (mg/L) after calculation by a microcomputer chip.http://www.yuanyice.com
