Reliability Control

Even with the advanced technology incorporated in this product, each instrument is given the full backing
of Klark Teknik’s “reliability control” which proves each product against a specification consistent with
the highest professional standards.  Only top quality components are used, and every unit is bench tested
and aligned before a burn-in period and final performance test.
