CA-31 & KF-31

For all companies that want to determine the moisture content of their products or manufacturing materials. These include the pharmaceutical industry, petrochemicals, energy, chemicals, food, food supplements and the agricultural sector.

With the CA-31 you can carry out coulometric Karl Fischer moisture determination. With the KF-31 you can carry out volumetric and, by adding a coulometric cell, coulometric Karl Fischer moisture analysis.

The methods differ in their measuring accuracy. Find out more about Karl Fischer titration here.

The systems are used without a control computer and evaluation software. All functions are directly integrated. Optional software is available for collecting measurement results and creating measurement reports. Data is exported via USB.

The Ca-31 and the KF-31 are used to measure the residual moisture in organic and inorganic solids, liquids, gases, liquid gases and viscous samples.

The measuring range of the coulometric measuring cell is 10 µg to 100 mg.

The sensitivity of the coulometric measuring cell is 0.1 µg _H2O.

The measuring range of the volumetric measuring cell is 0.1 – 999 mg _H2O.

The burette accuracy of the volumetric measuring cell is +/- 0.01 ml.

Of course, we will be happy to come to you and show you the appliance so that you can get to know the technology.

No, CA-31 and KF-31 have their own control units with color LCD touchscreen.

Yes, we offer a wide range of Aquamicron reagents.

Once your device has been installed, our service team will be available to provide you with detailed product training. Most questions will arise as you work, so we will also be able to help you with any questions that arise at a later date – at your premises or flexibly via an online meeting.

CA-31 and KF-31 are modular and conform to almost all relevant standard procedures of Karl Fischer determination.
