Product Introduction
COD measurement range 0~500mg/L, turbidity measurement range 0~200NTU.
Adopts modulated light signal to reduce visible light interference.
Dual optical path measurement compensates for the impact of turbidity on COD measurement.
Internally integrated self-cleaning system effectively prevents biological fouling.
The device adopts wide voltage power supply, DC 9~30V.
