S7130EC online ultrapure water conductivity controller/EC meter/conductivity electrode/Esensor/TDS meter

Applications：

Industrial online conductivity meter is a

microprocessor-based water quality online monitoring

control instrument. This instrument is widely used

in power plants, petrochemical industry, metallurgical

electronics, mining industry, paper industry, medicine,

food and beverage, water treatment, modern

agricultural planting and other industries.It is suitable

for softening water, raw water, steam condensate

water, seawater distillation and deionized water, etc.

It can continuously monitorand control the

conductivity, resistivity, TDS, salinity and temperature

of aqueous solutions.

Feature：

● LCD Display.

●Intelligent menu operation.

●Data Recording & Curve Display.

●Manual or automatic temperature compensation.

●Two sets of relay control switches.

●High & low alarm, and hysteresis control.

●4-20mA&RS485Multiple output modes.

●Display measurements, temperature, state, etc.on the same interface.

●Password protection function to prevent misoperationby non-staff.
