Features

Measurement functions are greatly improved Precision on ultra trace level moisture determination (lower than 10ug) is improved by a special measurement mode by continuous electrolysis. Less reagent and waste Single-chamber small size cell will require only 25mL of anode solution but no cathode, helpful to cut back cost and waste. Two KF channels run in parallel Combining one additional KF station with either volumetry or coulometry enables two different measurements to be performed at the same time! Color LCD touch panel with more informative and easy-to-operate display Current status, data and function keys are displayed on a 7.5" screen. All helpful and necessary information is always at hand! USB interface for data storage Results and parameters can be stored in a USB flash memory stick. Browse data by PC on a LAN connection Result data with curves can be viewed on your PC internet browsing program without optional software.
