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.
