  • Product Description

    ■ Features 

    ● Digital sensors, directly outputting RS-485 digital signals and supporting MODBUS/RTU.

    ● Dual-path measurement; compensation light sources at 254 nm and 550 nm to eliminate turbidity and coloration effects

    ● Imported UV254 LED cold light source, long life and small drift; filter design, low interference and stable.

    ● Measurable parameters include COD, TOC, turbidity and temperature without chemical reagents or sample digestion treatment.

    ● Small in size, with an integrated automatic cleaning brush inside to effectively prevent biological adhesion;

    ● Surface corrosion and passivation treatment

    ● Low power consumption of sensors, and internal circuit design to resist interference
