DDG9605
Online conductivity meter /TDS/ salinometer
8000 series industrial on-line conductivity meter is a water quality on-line monitoring and control instrument with microprocessor.
The instrument is widely used in power plants, petrochemical, metallurgical electronics, mining, paper industry, semiconductor, medicine, food and beverage, environmental protection water treatment, new agricultural planting and other industries;
Suitable for softening water, raw water, condensed water, sea water distillation and deionized water, etc.
The conductivity, salinity, TDS and temperature of aqueous solution were continuously monitored and controlled.
Instrument features:
● LCD LCD display
● Chinese/English intelligent menu operation
● a variety of signal output options
● manual or automatic temperature compensation
● two sets of relay control switches
● high limit, low limit, hysteresis control
● the same interface displays conductivity, temperature, state, etc
● with password protection to prevent non-staff misoperation
