Vibration Meter NVRM-200

Vibration Meter NVRM-200

Vibration Meter NVRM-200 is perfectly designed for easy on site vibration measurement of all rotating machinery for quality control, commissioning, and predictive maintenance purposes. It consists of a wide frequency range (10 Hz to 10 kHz) in acceleration mode that gives high quality accelerometer for accurate and repeatable measurements. Piezoelectric Transducer is used as a sensor in the device for high sensitivity. Three parameters that are; Velocity, Acceleration and Displacement can be displayed on one screen for 3-dimensional or 1-dimensional measurement.
