Optimum belt tension is one of the prerequisites for a maximum service life of the belt drive. The PRE-4040 tension meter is a high-precision optical measuring instrument that displays the relevant belt tension parameters such as frequency (Hz) or forces (N). It also includes operating instructions and displays in several languages.

It is a compact, convenient and universally usable tool that convinces with its easy and safe handling. It provides wear prediction of belts and pulleys and prevents damage to bearings and shafts, thus minimizing the risk of catastrophic downtime.
