The Measure it S2 tonearm scale is a high-precision electronic scale designed to measure a wide tracking force range up to 5.0 grams in 0.001 gram increments. The Measure it S2 has a solid aluminum housing with a 4-digit LCD display with backlight. Each Measure it S2 can be easily calibrated with the included calibration weight. If you are not sure whether the tracking pressure on the diamond tip is correct, the 4-digit display of this intelligent tool will reliably help. With the precise information about the current tracking force, you can prevent premature wear of the tracking diamond.
