Vibration meter VM-422 is a new model produced by the VVV-Group trademark. A vibrometer is a vibration measurement instrument, which is designed to determine the root-mean-square speed, displacement amplitude or acceleration of vibration of mechanical components and mechanisms. Determining these parameters makes it possible to determine the quality of both new mechanical components in production and to timely assess the technical condition of mechanical components during their operation. To determine vibration parameters, VM-422 uses a high-precision piezoelectric sensor, the voltage of which is converted into device readings using an electronic microprocessor. These readings are displayed on a color graphic screen, and the vibrometer is controlled using a graphic menu and three control buttons.

Vibration meter VVV-Group VM-422 has the following key features:

measurement of vibration parameters: vibration velocity, vibration acceleration and displacement amplitude;
vibration frequency measurement;
selection of the frequency range when measuring vibration acceleration;
backlit color graphic display;
memory for storing measurement results;
determination of maximum, minimum, average values;
battery charge indication;
LED flashlight for taking measurements in dimly lit areas.
