Recommendations for a good vibration measuring instrument.
Recommendations for a good vibration measuring instrument.
(OP)
I was looking to buy a instrument to measure vibrations (i.e. amplitude, velocity, and acceleration). I have found some fairly cheap stuff (which is always good
), but I wonder about its quality and I also am concerned that most of them I have been able to find cannot measure frequencies below 10 Hz. Therefore I am looking for recommendations. A recommendation for ground motion measurement is also welcome.

If you need higher frequency response, an accelerometer is likely a better option. They are cheap, but require separate dataloggers that can be pricey and difficult to program.

You might try the Modal Shop in Cincinnati. They also rent equipment.
