The Digital Vibration Tester Meter with LCD and Gauge Tester Analyzer The Vibration tester meter is one of the most useful tools in everyday machinery vibration monitoring. It measures acceleration (peak), displacement (peak to peak) velocity and revolution (R.P.M / RPM) with high accuracy and no guessing error. Easy to use and does not need any vibration analysis knowledge to operate and use this vibration meter. The digitally displayed vibration level is one of the best indications of machine running condition. Utilises an external accelerometer and magnetic base to improve frequency response and provide a more repeatable vibration reading. Frequency ranges are utilized for broad detection abilities.
