Application DataKarl Fischer Moisture Meters
CA-310 Moisture Meter Coulometric Titration
The new CA-310 is a convertible Karl Fischer moisture meter that can easily switched from coulometric to volumetric measurement or vice versa just by changing the titration cells. Titration cells can be connected up to 4 channels for simultaneous measurements.
The user friendly Main Controller with 8.4 Inch LCD touch screen will enable users to control and access measurement data of each cells fast and easy. The Main Controller and the Stirrer can be connected by either USB cable or wireless (option) for data communication. The lower limit of measurement range is 5μg H2O for coulometric measurement with good repeatability*. (*subject to ambient conditions)
Various types of options are available:
Vaporizers: VA-300 (New), VA-200, VA-210, VA-230, VA-121, VA-122, VG-200 and VA-236S
Options: Barcode reader for Karl Fischer Reagent, Battery unit, Foot switch, Optical start switch, Reagent exchange unit, Thermal / Impact printers, etc.
Features
Convertible function
Compatible stirrer allows both volumetric and coulometric method just by converting volumetric flask and coulometric cell. This feature enables wide range of applications at low initial cost.
4 simultaneous messages on one display
Connected channels can be viewed using tabs that display measurement status. All channels can be viewed on one display.
Lowest limit of quantitation 5μg H₂O
In dry atmosphere (e.g., in glove boxes) and microanalysis modes, the coulometric method achieves 5μg H₂O.
Ramp heating
Easily determine of the optimal heating temperature for unknown samples.
