Qualmark OVTT Vibration Tables
The OVTT (Qualmark Benchtop Repetitive-Shock Table) is the first stand-alone, table-top, repetitive-shock vibration system on the market. The OVTT system is ideal for No Fault Found (NFF) precipitation screens of field returns, repair verification, and random vibration test of small products. The Qualmark OVTT system utilizes our patented six-degree-of-freedom vibration technology and has reduced air requirements and low noise levels. The table-top configuration is easy to add to any laboratory and can be placed inside a thermal chamber for combined stress testing.
