ALTA Wireless Advanced Vibration Meter - AA Battery Powered, 900MHZ

The ALTA Wireless Advanced Vibration Meter uses an accelerometer to measure vibration and frequency on 3 axes. The sensor reports vibration (acceleration, velocity, displacement, or acceleration peak), frequency (Hz/RPM), and crest factor on all three axes. It also reports duty cycle (how much of the report interval that vibration was present), and temperature.
