Digital COD Sensor

Product features

■ Dual optical path :245nm and 550nm, can effectively eliminate the influence of turbidity and chroma.

■Ultraviolet absorption method determine the organic matter (such as COD TOC, etc.). It doesn’t requires reagents and digestion of the sample, with fast response speed – 10-second response (T90).

■ Cold light source UVLED, long life, small drift. Filter and PD receiver, no consumables, long life, small drift.

■ Standard automatic cleaning brush, can effectively prevent biological contamination.

■ With independent property rights and stable supply chain of key components, products with high cost performance.
