L&W Autoline Moisture | Automated water content measurement for paper and board

Are you looking for support or purchase information?

Why measure moisture?

Many basic properties of paper are greatly affected by moisture content.

Just a 1% variation in paper/ board moisture content can change the compression strength by up to 8%, making it an important factor that must be taken into consideration.

Accurate and reliable moisture measurement

L&W Autoline Moisture

L&W Autoline Moisture measures the water content in paper and board using the well-proven microwave method with double-frequency resonance. 

Why automate moisture testing?

Within the L&W Autoline, the test only takes a few seconds, instead of the hours needed for the traditional gravimetrical test. Plus, in stand-alone lab paper testing, it’s common that testing is done without proper conditioning to expedite results. 

L&W Autoline Moisture measures the moisture content on a large and representative sample in just a few seconds. The measurement results are not affected by curled materials, uneven surfaces or multilayer structures.
