CA-31 and KF-31

Karl Fischer moisture meters – Compact, convertable and cost-efficient

The Compact CA31 and KF31 Karl Fischer moisture meters provide cost efficient, convertible systems for both coulometric and volumetric measurements.

Simple, Fast and accurate Karl Fischer moisture meters

The portable CA-31 is a compact coulometric Karl Fischer moisture meter for the economic user. Designed to fill a dual role as a lab based or portable system the CA-31 has an optional carry case and battery for any location. The airtight, ground glass, one piece titration cell provides near zero background levels of moisture and coupled with the simple design and interface allows users immediate access to fast, accurate and precise Karl Fischer moisture measurements.

The compact and convertible KF-31 moisture meter is equipped with a built-in burette for volumetric karl fischer. By adding a coulometric cell the same KF-31 can also be used as a coulometric Karl Fischer. The KF-31 eliminates the need to buy 2 Karl Fischer instruments by providing a method for both coulometric and Volumetric Karl Fischer Measurements with just one compact unit.
