Product Description

Online Conductivity TDS Salinity Controller Water Quality Monitor 4-20mA RS485 Transmitter

>>Overview
The industrial online conductivity meter is a microprocessor-based water quality online monitoring and control instrument. This device is widely used across various industries including power plants, petrochemicals, metallurgy and electronics, mining, paper manufacturing, semiconductors, pharmaceuticals, food and beverage production, environmental water treatment, and modern agricultural cultivation. It is suitable for applications such as softened water, raw water, steam condensate, distilled seawater, and deionized water systems. The instrument enables continuous monitoring and control of key parameters including conductivity, resistivity, TDS (Total Dissolved Solids), salinity, and temperature in aqueous solutions.
