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.
>>Features
