BOQU Turbidity Probe Company

Product Overview

1) Product overview

Product Features

- Model: BOQU ZDYG-2088-01 Online Digital Turbidity Sensor (RS485, Modbus RTU).

Product Value

- Measurement principle: infrared light scattering (ISO 7027 method) with infrared absorption combination; output via photodetector and digital signal processing.

Product Advantages

- Mechanical/electrical: DC 12 V power, IP68/NEMA6P protection, standard 10 m cable (extendable to 100 m), sensor body in SUS316L + PVC (sea?water version available), fluorine rubber O?ring.

Application Scenarios

2) Product features

- Measurement ranges: 0.01–100 NTU (standard) or optional 0.01–4000 NTU.

- Resolution 0.01 NTU; accuracy: ±1% of reading or ±0.1 NTU (whichever is larger).

- Operating conditions: 5–60 °C, inlet pressure ≤ 0.4 MPa, relative humidity < 70% RH.

- Communication: RS485, Modbus RTU digital output (can provide standard digital output without extra controller).

- Built?in automatic cleaning brush with user?set cleaning intervals; self?diagnosis function.

- Double?beam infrared scattering spectrophotometer detection for high repeatability, stability and anti?interference performance.

3) Product value

- Reliable, continuous online turbidity monitoring for process control and regulatory compliance.

- Reduced downtime and maintenance costs thanks to automatic cleaning and robust materials.

- Accurate, color?insensitive turbidity readings (ISO 7027 infrared method) for consistent decision making.

- Easy integration into supervisory systems via standard RS485/Modbus digital output and long cable capability.

4) Product advantages

- Maintenance?friendly design (automatic cleaning brush and self?diagnosis).

- High measurement performance: fine resolution, wide range options, and strong accuracy.

- Robust construction and high ingress protection for long?term field use, including a seawater variant.

- Digital double?beam detection reduces interference and improves repeatability versus simple single?beam sensors.

- Ready for networked installations without additional controllers, simplifying system architecture.

5) Application scenarios

- Online turbidity monitoring in drinking water plants (raw water intake, sedimentation basins, finished water).

- Sewage and wastewater treatment plants for process control and discharge monitoring.

- Industrial process water and wastewater monitoring across manufacturing applications.

- Coastal/marine monitoring where the seawater version is required.

- Any application requiring continuous, accurate turbidity data and easy integration into SCADA/automation systems.
