Cou-Lo Aquamax KF Moisture Meter

Cou-Lo Aquamax KF moisture meters have been specifically designed for the determination of water content. Combining coulometry with the Karl Fischer method, Aquamax KF titrators determine the water content of samples by measuring the amount of electrolysis current necessary to produce the required iodine – this is an absolute technique which does not require the calibration of reagents.

Aquamax KF titrators have been developed in response to many suggestions and comments from our customers in routine laboratories, off-shore platforms and in the field. The built-in battery and optional carry case provide the versatility required by the laboratory and also the ease of use and portability required by the field engineer.

The Aquamax KF offers many advantages over competition. Easy to use – simple to programme so that only a single button needs to be pressed for a titration, everything else is automatic. Complete with built-in high speed printer, everything in a single footprint, small space requirement. Results can also be downloaded via the Results Manager software package onto a pc spreadsheet.

Results Manager

  • Can download results directly from the titrator through a serial port connection, or open result files previously saved to disk.
  • Contains all necessary cables, connections, installation cd and user manual.
  • To use the titrator outside of the laboratory and do not have a pc or laptop with them, our built-in xd memory card system will store all results.
  • Can then be connected to our card reader to download stored data through Results Manager when returning to the laboratory.
  • Is supplied as a standard item included with the Aquamax KF.
