Vibrometer CM-21

With stethoscope, pyrometer, tachometer functions

Vibration and operation parameters are the most frequently measured magnitudes for the condition monitoring

applications. Multifunctional vibrometer CM-21 allows all these measurements.

CM-21 is used for periodic monitoring of vibration according to ISO 10816 in all standard frequency bands.

Additionally it allows measurements of additional parameters for condition monitoring in rotating machines.

These are high frequency vibration levels, temperature, peak factor.
