Vibration Meter NVRM-302 operates within a temperature range of 0 to 50°C and humidity levels below 90% RH. It uses a piezoelectric transducer that produces an electric charge under mechanical stress. This unit ensures reliable performance with an accuracy of 5% of the reading plus 2 digits. It allows real-time audio monitoring through optional headphone connectivity. Our meter is ideal for rapid, on-site vibration checks of all types of rotating machinery.
