Portable Vibration Meter
VIBRA-CHECK™ VM2800 and VM3800
The economical and compact VIBRA-CHECK™ Vibration Meter is an
ideal tool for obtaining spot measurements of machinery vibration.
These units are suitable upgrades to the model SH2000 meter.
All three useful measurements are possible. Displacement, velocity, and
acceleration modes allow a user to perform basic vibration analysis.
The robust high temperature accelerometer sensor has a
removable magnetic mounting base for attachment of a stinger. The
sensor is internally protected against thermal shock, electrical noise and
amplitude overload.

The handy carrying pouch keeps the meter out of the way, yet ready for
use. When it’s time to take a reading, simply place the accelerometer
on your machine and tilt the pouch up to view display.
