Riverstone Audio Precision Record Level Digital Turntable Stylus Force Scale Gauge for Tonearm Phono Cartridge VTF, 0.005g Resolution (Silver)

Product description

• A Professional digital tracking force scale designed for vinyl record purist's interested in precise measurement of vertical tracking force (VTF) at the correct vertical tracking angle (VTA). When used with the detachable cantilevered extension arm, the scale 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.
• For optimal accuracy, tracking force should be measured at the same vertical position as the record surface. With Riverstone's VTF gauge's patented design (US Patent D878232), 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 measurement sensor provides 0.005 g resolution and accurate measurements over the entire calibration range. To ensure accurate readings, our VTF scales undergo a rigorous multi-point calibration procedure to verify their linearity, repeatability and accuracy. We have confidence in our products and provide TWO calibration masses (5g and 20g) to verify your readings at any time and also allow for future re-calibration if needed.
• Manufactured using non-magnetic materials to minimize interactions with MM and MC cartridges used with most turntables. The housing of the VTF scale is manufactured from a durable ABS polymer. The cantilevered extension-arm is machined from a non-ferromagnetic grade stainless steel and the locking screw of the extension arm is machined from aluminum and brass. A polymer pad protects the stylus tip and allows centering of the stylus on the measurement platform.
• Riverstone Audio VTF scales are covered by our no-nonsense THREE-YEAR WARRANTY. Two levels of battery protection are used auto-turnoff of the display and auto powering off of the circuit after 60 to 120 seconds of inactivity. A detailed instruction manual (in English) is provided. Includes a tin storage box to protect the VTF scale when not in use. PLEASE NOTE *****Requires one AAA ALKALINE battery (SORRY, BATTERY IS NOT INCLUDED)*****.
