Water Quality Analysis Online Turbidity Probe RS485 Turbidity
Sensor 4-20mA Output Turbidity Meter Accuracy
Principle
Our turbidity sensors use fiber optic technology to provide
superior repeatability and stability, and are less susceptible to
ambient light. The automatic cleaning brush with the sensor can
effectively eliminate air bubbles and reduce the influence of
contamination on the measurement. It has a longer maintenance
period and maintains excellent stability for long-term online use.
Features
* Digital sensor, RS-485 output, support MODBUS
* With automatic cleaning brush to prevent contamination and
eliminate air bubbles
* Strong anti-interference ability, free from ambient light and
chromaticity
* 90° scattered light principle, with fiber optic technology for
better repeatability

Maintenance method
①The outer surface of the sensor: clean the outer surface of the
sensor with tap water. If there are still debris remaining, wipe it
with a moist soft cloth. For some stubborn dirt, you can add some
cleaning fluid to the tap water to rinse.
②Check the cable of the sensor: the cable should not be taut during
normal operation, otherwise the internal wires of the cable may
break, causing the sensor to fail to work normally.
③Check whether the electrode or light window of the sensor is
dirty, whether the cleaning brush is normal, and whether the
electrode is normal.
④Check whether the cleaning brush (if any) of the sensor is damaged
and whether it can work normally.
⑤Continuous use for more than 18 months, (as the case may be)
return to the factory to replace the dynamic sealing device.
