For decades, one style of analyzer/balancer has been used by more maintenance professionals than any other. That instrument is the Vibration Analyzer with Strobe Light for vibration analysis and in-place dynamic balancing. These instruments are known for their rugged durability, reliable operation and accurate readings. The Tunable Filter and Strobe Light are a favorite with operators - easy to use and more convenient than digital filters and laser photo tachs. These analyzer/balancers allow operators to dynamically balance rotors of any size and shape.
