Vibration Meter NVRM-201 uses a 3-axis piezoelectric accelerometer for precise readings with an accuracy of 5% of the reading + 2 digits. It offers a wide frequency range in acceleration mode from 10Hz to 10kHz. This unit features a high-quality accelerometer that guarantees consistent and reliable results. It displays three critical parameters simultaneously on a single screen for comprehensive analysis. Our meter is powered by two 1.5V AAA (UM-3) batteries, ensuring portability for on-site use.
