Feature: 1. [3 Measurement Modes] This digital vibration meter offers acceleration range of 0.1 to 199.9m/s2 (peak), velocity range of 0.1 to 199.9mm/s (true RMS), and displacement range of 0.001 to 1.999mm (peak to peak) for a comprehensive testing. 2. [Long Probe Design] Equipped with a long probe, this digital vibrometer can measure points that are out of touch for shorter probes, providing convenient vibration measurements. 3. [Interchangeable Probe] The digital vibration tester allows for probe replacement, enabling flexible measurement on various surfaces. Users can choose different probes based on measurement requirements to reliably assess equipment. 4. [Wide Frequency Range] Covering frequencies from 10Hz to 10KHz, this digital vibration detector ensures accurate measurement across a broad spectrum of vibration frequencies. 5. [Rapid Data Refresh] With a data refresh time of 500ms, this digital vibration measurement tool provides timely and accurate updates for efficient monitoring and analysis.
