    I have a collection of 2 kinds of Tuned Reed Vibration gauges one type measures frequency of AC supplied and ranges from 20 hz to 400hz and Lo volt to !25. All reeds vibrate but I cannot test the 400 hz

    The other Tuned Reed types are non electric and sense the RPM by making contact with the casing of the motor, they all work very well but I could not test one that on that had a very high RPM about 7000 RPM most of the meters measure from 1700 to 3000 RPM

    At one time I collected these and other meters such as Galvanometers and other strange old devices,
    This is not a business, I just collect.

    I can post pictures if I knew the file size that this forum allows or I could send them to your home email

    Thanks ..colum
