The KTU310 integrated on-line turbidimeter is designed and made by the principle of scattering light turbidimeter. When a beam of light enters a water sample, the light is scattered by the turbidity material in the water sample. The turbidity in the water sample can be calculated by measuring the intensity of the scattered light in the vertical direction of the incident light and comparing it with the internal calibration value, the final value is output after linearization.
90 ° angle scattering principle, built-in temperature sensor
Support RS-485, Modbus/RTU protocol
Fiber structure, strong anti-interference ability of external light
Infrared LED light source, high stability
IP68, shield, water depth, 20 meters
Convenient, fast, stable and easy to maintain

The cable is a 4-core twisted pair shielded wire defined in line sequence:
Red wire -- power cord (12V-24VDC)
Black line (GND)
Blue Line -- 485a
White line -- 485b
Before electrification, the wiring sequence should be carefully checked to avoid unnecessary losses caused by wiring errors.
Wiring instructions: Consider the cable long-term immersion in water (including seawater) or exposed to air, all wiring are required to do waterproof treatment, customer cable should have a certain anti-corrosion ability.
6.1.1 Maintenance Schedule
Measuring the cleanliness of windows is important for maintaining accurate readings.
| Maintenance task | Recommended maintenance frequency |
| Calibration of sensors (if required by competent authority) | According to the maintenance schedule required by the competent authority |
6.1.2 Maintenance Methods
Sensor outer surface: clean the sensor outer surface with tap water, if there is still debris residue, wipe with a damp soft cloth, for some stubborn dirt, you can add some household cleaning liquid in tap water to clean.
Check the wire of the sensor: the wire should not be taut when working normally, otherwise it is easy to break the wire inside the wire and make the sensor can not work normally.
Check if the measuring window of the sensor is dirty and the cleaning brush is normal.
6.1.3 Points to Note
The probe contains sensitive optical and electronic components. Make sure the probe doesn’t get hit by any heavy machinery. There are no parts inside the probe that require user maintenance.
Zero-point calibration: take a proper amount of zero-turbidity liquid with a large beaker and place the sensor vertically in the solution. The front of the sensor should be at least 10 cm from the bottom of the Beaker. zero-point calibration should be carried out after 3 ~ 5 minutes of numerical stabilization. Instruction Reference Appendix.
Slope calibration: the sensor probe is placed in standard solution, the sensor front end is at least 10 cm from the bottom of the Beaker, and slope calibration is carried out after 3 ~ 5 minutes of numerical stabilization. Instruction Reference Appendix.
| Questions | Probable cause | Solution |
| The interface can not be connected or the measurement results are not displayed | Measurement value is too high, too low or value continues to be unstable | Reconnect the controller to the cable |
| Cable failure | Please contact us | |
| Measurement value is too high, too low or value continues to be unstable | The sensor window is attached to something | Clean the surface of the sensor window |
