Excellent moisture content tester even with the learning curve.
Rating: 4.0

  • Application Area: Moisture Content

"I've used Mettler-Toledo coulometric KF units for over 7 years. They are good instruments, though there is a bit of a learning curve for sample analysis. The literature says the coulometric version is good for moisture content less than 5%, however, when you talk to Mettler they recommend staying below 1-2%.

The instrument can be pretty picky so you have to monitor it closely. I am surprised that there is no solvent life monitor on this unit. The previous version had it but for some reason this new updated version does not have it, which is pretty frustrating. Especially when Mettler couldn't give me a good process for determining when to change the solvent, and the fact that we were told when we purchased the unit that it did have a solvent life monitor only to find out it did not have a monitor. The solvent manager is really great and makes changing solvent easy with no mess.

Using it with the attached oven is also another learning curve but really expands your sample capabilities.

It would be nice if you could customize the permissions for the tech vs admin user accounts but the two profiles are set. Tech support via email has been pretty good. Sometimes you have to email a couple times to get a fast response but all my questions have been answered.

The Routine Titrator

The Routine Karl Fischer Coulometer combines fast and precise water content determination with very simple operation. Samples from any industry with water content between 1 ppm and 5% are analyzed in single measurements or as sample series with statistics.


One Click® User Interface

The large color touchscreen features the simple-to-understand and fast-to-operate One Click user interface. All users have their own homescreen with dedicated shortcut buttons to directly start specific routine tasks.

Solvent Manager

Users are protected against contact with chemicals using the Solvent Manager liquid handling device. It is fully controlled by the titrator and allows reagents to be removed with minimal user interaction.

Diaphragmless cell

The user has the choice of a current generator cell with or without a diaphragm. For most samples the cell without a diaphragm offers more convenience, as no catholyte is needed. Due to the unique design, the diaphragmless cell even meets the demands of very precise low water content determinations.

PC software LabX® Titration

Full control over the titrator, secure database archiving, networking, efficient result management with control charts and individual search filters or rapid and clear method development are only some aspects of the powerful LabX Titration PC software.
