MK-64 Online Vibrometer

Online vibrometer that accurately detects equipment abnormalities
Higher visibility with the new digital meter

Digital meter display for higher visibility
Enables checking of the signal level instantly.
Easy alarm setting with digital display
You can easily set any value in 1% units using the digital setting switch.
Level signal and alarm output functions
The vibrometer is equipped with level signal (4 to 20 mA DC) and alarm output (relay output).
Precise diagnosis available by connecting the portable diagnostic instrument
By connecting a MK-210HEII Vibration Data Management System, precise diagnosis, frequency analysis, and report output are made available.
Power source voltages for global application
MK-64 supports power source voltages ranging from 85 to 264 VAC for global application.


Continuous vibration monitoring of a motor, pump or fan
Collecting vibration data for a DCS
Equipment diagnosis for a rotating machine
