For deejays and others dedicated to the sound of vinyl. The Shure SFG-2 Stylus Tracking Force Gauge is the industry standard for turntables. This simple-to-use measuring device was developed to give listeners a way to insure against the problems caused by improper tracking force settings, which include mistracking, excessive record and tip wear, and poor sound reproduction. This gauge is a highly accurate beam balance instrument designed to measure the actual downward force exerted by a stylus on a record over the range of 0.5 to 3.0 grammes. Each gauge is individually calibrated, and displays readings in 0.05 gramme increments in order to provide a precise measurement of stylus tracking force.
