Automatic Coulometric Karl Fischer Titrators AQ-2200 Series

 

AQUACOUNTER® offers a new style of Karl Fischer Titrator that is both economical and eco-friendly!!

The AQ-2200 Karl Fischer coulometric high-end titrator is ideal for the trace level moisture determination with its excellent capability and upgraded performance.
The new design comes with a built-in printer and a wide color LCD touch panel but yet compact. With enhanced memory capacity, results and parameters can be stored in a USB memory stick, or can be viewed by a PC with a LAN connection.

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.
