Industrial on-line conductivity meter is an on-line water quality monitoring and control instrument with microprocessor.The instrument is widely used in power plant, petrochemical, metallurgy, electronics, mining, paper, semiconductor, medicine, food and beverage, environmental water treatment, new agricultural planting and other industries.Suitable for softened water, raw water, steam condensate, sea water distillation and deionized water, etc.The conductivity value, resistivity value, TDS value, salinity and temperature value of aqueous solution were continuously monitored and controlled.
Instrument features:
● large LCD screen color LCD display
● smart menu operation
● data record & curve display
● manual or automatic temperature compensation
● three groups of relay control switches
● high limit, low limit, hysteresis control
● 4-20ma &RS485 multiple output modes
● the same interface displays the measured value, temperature, current value, etc
● can set password protection to prevent non-staff error operation
