Benchtop Digital 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.
