Shure SFG2 - TRACKING FORCE MEASUREMENT SCALE

(This text is machine translated) Shure SFG 2 is an extremely precise scale designed to measure the downward force exerted by a needle on a record, in the range between 0.5 and 3.0 grams. Each instrument is individually calibrated in the factory, allows measurements to be made in increments of 0.05 grams and provides the precise value of the Tracking Force, or rather the "weight" to be applied on the stylus to keep it correctly in the groove.
