Product Introduction
The BOD sensor uses an advanced deep-ultraviolet UV LED cold light source, featuring a long service life and small drift. It adopts internationally universal advanced technology and a proven high-precision ultraviolet absorption method. There is no need for sample pretreatment, and the reaction speed is fast. No reagents, no sampling equipment are required. The sensor has a mechanical self-cleaning function and uses a 550nm compensation light source, which can effectively eliminate the influence of turbidity and color on the measurement.
