Vibration Meter NVRM-204 features a piezoelectric transducer for precise vibration and acceleration measurements. It operates within a temperature range of 0°C to 50°C and humidity below 90% RH. This unit combines photo tachometer and contact tachometer functions for accurate rotation. It includes headphones for live sound detection and monitoring. Our meter displays test parameters clearly through a user-friendly digital screen.
