Multiparameter Water Quality Meter


River Monitoring Water Treatment Sensor

Product Description

Online multi-parameter sensor can integrate 11 sensor probes for sewage treatment wastewater treatment river monitoring 

Product Description


The D2100 series multi-parameter water quality sensor (seven parameters) is designed in an all-in-one configuration. Each sensor has a waterproof connector. The calibration data is stored in the sensor and can be calibrated and replaced in the field. Up to 6 Laoshan digital sensors can be connected at the same time. Optional fluorescence dissolved oxygen, four-electrode conductivity, fiber turbidity, digital pH, digital ORP, chlorophyll, water oil and ammonia nitrogen sensor. Equipped with an automatic cleaning device to eliminate air bubbles and prevent microbial growth, it can easily meet the needs of various water environment monitoring such as rivers, lakes, oceans and groundwater. It has excellent reliability and can be operated in an unattended environment for several months without maintenance..



² Digital sensor, RS485 output, support MODBUS

² All calibration parameters are stored in the sensor, and each probe has a waterproof connector for easy insertion and removal.

² Equipped with automatic cleaning device, it can effectively remove the surface contamination of the sensor, prevent the growth of microorganisms, more accurate and lower maintenance.

² Alternatively luminescent dissolved oxygen, four-electrode conductivity, optical turbidity, the pH digital, digital ORP, chlorophyll , oil in water and ammonia nitrogen

² Sensor for long-term online monitoring.

² The all-in-one design allows for the simultaneous connection of six probes and seven parameters.

Maintenance method

Sensor maintenance

  • Check: Check the sensor head for dirt and microorganisms, whether the casing and sensor surface are damaged, whether the cable is normal, whether the test data is normal, and whether the consumables are damaged.
  • Cleaning: Use tap water to clean the outer surface of the sensor. If debris remains, wipe it with a moist soft cloth. For some stubborn dirt, you can add some household washing solution to the tap water to clean it.
  • Calibration: Perform single or two-point calibration on the sensor. Select the appropriate standard solution according to the corresponding sensor.


The probe contains sensitive optical and electronic components. Make sure that the probe is not subject to severe mechanical impact. There are no parts in the probe that require user maintenance.
