RS485 Modbus Turbidity Water Quality Sensor AMT-ZD300

RS485 Modbus Turbidity Water Quality Sensor - AMT-ZD300

Product Model: AMT-ZD300

Product Introduction

AMT-ZD300

Smart Turbidity Sensor

Intelligent turbidity sensor (AMT-ZD300) is a device usingRS485Communication interface and standardModbusprotocols. This sensor

The sensor uses wavelength860nminfraredLEDas the light source, not affected by the color of the water sample, using90°Scattering method, complies withISO 7027Intelligent water quality sensor with international standards and

USEPA 180.1US environmental protection standards. This sensor has the advantages of maintenance-free operation and strong anti-interference capability. It is widely used in surface water, municipal sewage,

Industrial wastewater, sewage treatment, water treatment plants, process control, and other fields

Fiber optic structure, strong resistance to external light interference;

Advanced circuit design, high measurement accuracy, stable performance;

Optical principle, high sensitivity, good selectivity, rapid measurement;

adopts90° angle scattered light principle, built-in temperature monitoring sensor;

Compact size, easy installation, capable of online uninterrupted water quality monitoring;

Main Application Areas

  • Drinking Water Treatment — Monitor turbidity levels in raw water, sedimentation, filtration, and finished water to ensure compliance with drinking water standards.
  • Wastewater Treatment — Track turbidity in influent, aeration tanks, and effluent to optimize treatment processes and meet discharge regulations.
  • Industrial Process Water — Control water quality in cooling towers, boilers, and manufacturing processes to prevent scaling, corrosion, and product contamination.
  • Environmental Water Monitoring — Measure turbidity in rivers, lakes, and reservoirs for ecological research, pollution tracking, and regulatory reporting.
  • Aquaculture — Maintain optimal water clarity for fish and shrimp farming to support healthy growth and reduce disease risk.
