DDS-W series conductivity meter are an easy-use basic meters
which used for measuring the electrical conductivity of liquids.
Automatic Calibration:
The meters can calibrate 1 point in each of the measuring ranges.
From Setup Menu, choose calibration and immerse the electrode
into standard calibration solution,press ENTER key and meter is
automatically calibrated.
Auto-Ranging:
The meters have auto-range function for measuring conductivity.
Upon immersing conductivity cell into sample solution, the meter
will immediately displays the values in appropriate measurement
range for accuracy.
Adjustable Temperature Coefficient:
Various ions may have different temperature coefficients, The meters
can set the temperature coefficient between 0.0 and 3.9% in degrees
Centigrade for optimum accuracy.
Adjustable Cell Constant:
The meters have 3 cell constants for measuring requirements. Once a
cell constant has its calibration set, it is saved and does not require
re-calibration when switching sensors.
Automatic or Manual Temperature Compensation:
The meters provides manual or automatic temperature compensation
for optimum accuracy under variable temperature conditions.
Fluid Resistant Housing and Swivel Electrode Holder:
The integrated plastic housing and keypad is sealed to protect against
accidental spills. The electrode holder arm is rapidly switched to both
sides and swivels and articulates for convenient use and positioning.
