Big succes at the „OPTATEC“ fair 2018 in Frankfurt (15.-17.5.)!

Such a large number of visitors we didn`t have every year..

The prototype kilo is the standard for all masses. The 129-year-old „international kilogram prototype“ hast lost some weight recently, however. The world of meteorologists is in uproar. A new definition for the kilogram was needed. Hauser Optik plays an important role in this.
