Vibration Meter-RVM4000


Used for measuring periodic motion,to check the imbalance and deflecting of moving machinery. Also can be used as contact tachometer and photo tachometer.



•  In accordance with ISO 2954,used for periodic measurements, to detect out-of-balance, misalignment and other mechanical faults in rotating machines.
•  Specially designed for easy on site vibration measurement of all rotating machinery for quality control, commissioning, and predictive maintenance purposes.
•  Multifunctional, one instrument combines Photo Tachometer & Contact Tachometer. Be able to measure rotation rate RPM(r/min) & Frequency Hz.
•  Individual high quality accelerometer for accurate and repeatable measurements.
•  Wide frequency range (10Hz~10kHz) in acceleration mode.
•  Optional headphones for use as electronic stethoscope.
•  Bearing condition monitoring function.
•  Use USB/RS-232 data output to connect with PC.
•  Provide Bluetooth data output choice.
