DuBan Vibration Tachometer

* Complies with international standard ISO2954, used for periodic motion measurement to detect imbalance and misalignment in moving machinery.
* Specifically designed for on-site measurement of various mechanical vibrations to provide data for quality control, operational time, and proactive equipment maintenance.
* Multi-functional meter: one instrument can be used as a photoelectric tachometer for non-contact measurement, or as a contact tachometer for contact measurement. Capable of measuring RPM and frequency in Hz.
* Utilizes high-performance accelerometers for accurate and repeatable measurements.
* Converts vibration signals using piezoelectric acceleration sensors.
* Features bearing condition measurement functionality.
* LCD display, lightweight, and simple operation for ease of use.
* Wide frequency range, up to 10-10KHz in acceleration mode.
* Equipped with AC signal output for auscultation and recording.
* Optional headphones can be used as a stethoscope.

* With optional RS-232c software and cable, it can communicate with a PC for printing and statistical functions.
