Product Introduction


The AMT-ZD300 intelligent turbidity sensor is a smart water quality sensor with RS485 communication interface and standard Modbus protocol. The sensor uses an infrared LED of a specific wavelength as the light source, unaffected by water sample color, and adopts the 90° scattering method, complying with ISO 7027 international standard and USEPA 180.1 US environmental standard.
The AMT-ZD300 intelligent turbidity sensor has advantages such as self-cleaning, maintenance-free, and strong anti-interference capability. It is widely used in surface water, municipal sewage, industrial wastewater, sewage treatment, water plants, process control, and other fields.

Main Application Areas

  • Wastewater Treatment — Monitor turbidity in effluent and influent to ensure compliance and optimize treatment processes.
  • Drinking Water Plants — Ensure water quality by continuously measuring turbidity levels in raw and treated water.
  • Environmental Monitoring — Track turbidity in rivers, lakes, and reservoirs to assess water clarity and pollution levels.
  • Industrial Process Control — Monitor turbidity in cooling water, boiler feed water, and other industrial processes to prevent scaling and fouling.
