Product Introduction

AMT-ZD300
Online turbidity sensor


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.
