DD-W6526 Conductivity/Resistivity/TDS/Salinity

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 monitor

and 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.

●Three 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.
