Product Introduction
Smart-Conductivity-Sensor-01
Conductivity Water Quality Sensor
AMT/-DDL300
The intelligent conductivity sensor (AMT-DDL300) is a smart water quality sensor for conductivity that uses an RS485 communication interface and the standard Modbus protocol. It provides conductivity measurements suitable for low, medium, and high ranges, with electrode constants from 0.1 to 10 cm⁻¹. Electrode materials include graphite, platinum, and stainless steel, and it can measure conductivity, TDS, and salinity. The corrosion-resistant housing, built-in Pt1000 temperature sensor, and compensation algorithm make it suitable for various harsh working environments. This sensor features good accuracy, linearity, and stable electrode constants. It is widely used in surface water monitoring, industrial wastewater and municipal sewage monitoring, water treatment industry, boiler return water monitoring, deionization process monitoring, reverse osmosis monitoring of seawater, brine, aquaculture water monitoring, and more.
