Online water turbidity Controller ZS-600 Turbidity Water Quality Testing

Product Introduction：

Online turbidity is the degree of resistance that occurs when suspended solids in the water pass through light. The soil contains mud, silt, fine organic matter and other microorganisms and colloids to give turbidity in the water. After the light wave transmitted by the transmitter on the sensor is absorbed, reflected and scattered by the measured object during transmission, a part of the transmitted light can be irradiated onto the detector in the 180° direction, and a part of the scattered light is scattered to the detector in the 90° direction. The intensity of the light received on the detectors in the 180° and 90° directions is related to the turbidity of the measured sewage. Therefore, the turbidity of the sewage can be calculated by measuring the intensity of the transmitted and scattered light.

Main Features：

Large screen dot matrix LCD display, support Chinese and English menu (mutual switching).

Built-in bubble elimination system (flow-through type) to improve measurement accuracy and stability.

Good reproducibility, not affected by sample water flow rate and pressure (submerged type).

Using a stable invisible near-monochromatic infrared light source, avoiding the interference of chromaticity in the liquid and external visible light on the sensor measurement; and built-in luminosity compensation to improve measurement accuracy.

Featuring water storage function to ensure that there are water samples in the circulation tank inside the sensor for 24 hours (flow-through type).

Using the latest detection technology to avoid the interference of external light, strong anti-interference ability (submerged type).

Using quartz glass lens with extremely high light transmittance on the optical path, the transmission and reception of infrared light waves are more stable.

Communication function (optional): With RS-485 communication interface (partially compatible with MODBUS protocol), the value corresponding to 4-20 mA current output can be set arbitrarily.

Photoelectric isolation 4-20mA current output.

Relay lag value can be set freely, avoid frequent action of switch relay, and with function of setting the replay on and off.

Using multi-point correction method.

The automatic cleaning interval can be set freely (only sensor support that ).

Watchdog function: to ensure that the meter will not crash.

Power off protection>10 years.
