Portable Handheld Vibration MeterAccurately measures vibration velocity and acceleration. The level of vibration is a useful guide to the balance, alignment and general condition of pumps, motors, and other machinery. Poor balance, misalignment, and looseness results in higher levels of vibration and indicates maintenance is required for operational as well as safety reasons. The large display indicates RMS, Peak, min max, hold, low battery, and features an auto power off. Comes
