Proceq’s PaperSchmidt is the first rebound hammer designed specifically for paper roll hardness testing. Extensive field tests carried out at major manufacturers and converters in the U.S. and Europe have consistently shown that it provides previously unachievable roll-profiling accuracy and repeatability, according to Proceq.

The instrument is fully compliant with the TAPPI T834 om-07 standard used in North America to regulate roll hardness testing and it delivers instantly all of the key parameters required for assessing the quality of paper rolls.

The PaperSchmidt has three unique features. It has a high compliance plunger and a innovative measurement principle that is independent of the angle of impact. This gives the PaperSchmidt best-in-class roll profiling performance.

In addition, the paper roll profile can be viewed directly on the integrated display. The instrument provides an automatic calculation of the average paper roll hardness, the range and standard deviation.

Finally, robust construction, a sealing system, and specially treated impact plungers greatly extend the lifetime of the instrument.
