DDS-W series Precision Conductivity Meter

Detailed Product Description

The DDS-W series conductivity meters measure the

capacity of ions in an aqueous solution to carry

electrical current.As the ranges in aqueous solutions

are usually small, the basic units of measurements

are milliSiemens/cm (mS/cm) and microSiemens/cm

(uS/cm).

Conductivity is used widely to determine the level of

impurities in water supplies for domestic consumption

as well as industrial use. Industries that employ this

method include the chemical, semi-conductor, power

generation, hospitals,food and beverage, mining,

electroplating, pulp and paper, petroleum and marine

industries.

Microprocessor-based

With a microprocessor chip inside and all parts of the

apparatus jointed with SMT technology, the DDS-W

series meter provides high performance and good

stability.

Adjustable Cell Constant

Adjusts the reading on the display to reffect use of a

cell with a constant.

Adjustable Temperature Coefficients

The TDS (Total Dissolved Solid) of certain samples,

such as alcohols and pure water, are affected by

changes in temperature.

An adjustable temperature coefficient allows the

user to compensate for temperature changes on the

solution being measured.

Auto-Ranging

Meter automatically selects the appropriate range for

measurement. There is no need to change the dial,

multiply values on the display, or turn the potentiometer.

Temperature Compensation

A cell with built-in temperature sensor allows the

meter to make adjustments to the conductivity

readings based on changes in solution temperature.

Large LCD Display

Large customized LCD(Liquid Crystal Display) with

simultaneous display of the measured value is easy

to read.

Selectable cell constants let you use k=1 cells for

general purpose, k=0.1 cells for high purity water,or

k=10 cells for brines or other concentrated solutions.
