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