**********A Professional digital tracking force gauge designed for vinyl record purist's interested in precise measurement of vertical tracking force (VTF) at the correct vertical height (height changes the vertical tracking angle VTA of a tonearm). When used with the detachable cantilevered extension arm, the gauge closely approximates the vertical position of the stylus on the surface of a vinyl record when it is playing on a turntable - providing accurate RECORD-LEVEL measurements of tracking force. *****For optimal accuracy, tracking force should be measured at the same vertical position as the record surface. With Riverstone's VTF gauge, tracking force is measured 2 mm - 3 mm from the surface of a turntable mat - the height of a stylus tip resting on an LP record (LP's have a thickness range of 1.9 - 2.9 mm).
With less expensive gauges, the measurement distance is typically 6 mm to 9 mm. *****Precision strain gauge sensor provides 0.005 g measurement resolution and accurate measur
