Product Summary<\/h2>\n

Model OST-727 is a measuring instrument which measures displacement of a cone paper excited by a drive speaker with a displacement sensor, and sets frequency at the displacement peak value to Fo according to direct method. This equipment judges a cone paper to be pass or no pass about Fo frequency by setting of an upper – lower allowance.<\/p>\n
