Model:

Features: •Measure COD value in water with free hydroxide radical produced by electrode. The instrument uses sodium sulphate and glucose solution without secondary pollution, dispensed with such harmful and dangerous chemical substance as potassium dichromate and concentrated sulfuric acid.
New-type sampling system, dispensed with frequent maintenance and cleanness.
Touch screen control, Chinese operation interface and simple operation.
Fast analysis speed: 6minutes/time
