Stability is the fundamental prerequisite for all measurement. 

Without stability, any measurement becomes invalid.”

STA is built for stable measurement, large load capacity spindle axis, heavy duty turntable and other core components are all designed with more than 300% surplus rigidity, ensuring the instrument a long-term stable measurement performance.

Except for stable measurement of small precision workpieces, with the high rigidity frame structure and core components, STA also capable of large and heavy workpieces, such as spindle sleeves, shafts, gear shafts, crankshafts, and other long shaft type workpieces measurement.”

Equipped with advanced RSP automatic measuring software system, STA frees operator intervention, makes complex measurement to simple works.
