DDS-W
SERIES MICROPROCESSOR CONDUCTIVITY METER
Single Point Push-Button Calibration:
DDS-W series with single point calibration function, you need only
set conductivity value of the calibration solution at 25oC
and immerse conductivity electrode into solution, then press [ENTER]
key, the meter will calibrated automatically.
Auto-Ranging for Conductivity:
The meter with auto-ranging function when measure conductivity.
After electrode immersed in solution, the meter will fast response
and convert range.
Auto Temperature Compensation:
DDS-12DW will recognize the temperature sensor automatically and
measure temperature after temperature sensor connected to the meter.
If the conductivity electrode connected to it, the meter will
enter automatic temperature
compensation.
Adjustable Temperature Coefficient:
Different ion solution usually have different temperature
coefficient, setting temperature coefficient correctly is very
important to measurement, DDS-W series can be set in the range of 0
to 3.9%per centigrade degree.
Adjustable Cell Constant:
When measuring higher or lower
conductivity solution, you should choose conductivity electrode with
different constant. The meter with three
cell constant (0.1,1,10) for your choice.
What's
included:
DJS-1 conductivity electrode(K=1),
electrode holder, 9V power adapters, temperature probe (only for
