The Pro-Ject Measure it S2 sits at the top of Pro-Ject’s range of digital stylus tracking force gauges, above the entry-level Measure it E. Where the E offers ±0.002 g resolution in a compact plastic body, the S2 steps up to ±0.001 g resolution and houses its electronics in a solid aluminium enclosure — a meaningful upgrade for anyone who wants the most precise cartridge setup possible.
Precision Measurement
The S2 measures stylus tracking forces across a 0–5 g range with a resolution of ±0.001 g, displayed on a backlit four-digit LCD. This level of precision allows fine-tuning of tracking force to the manufacturer’s recommended setting, which directly affects stylus wear, record wear, and the balance between tracking ability and distortion. Four weighing modes are available — gram, ounce, pennyweight, and carat — with the gram scale calibrated at 1 g = 10 mN for those who prefer to work in millinewtons.
Construction and Calibration
The solid aluminium housing provides a stable, rigid platform for the internal load cell. An auto-calibration function is built in, using the supplied 5 g reference weight to zero the scale before each session. The backlit display remains active for 60 seconds before the unit powers down automatically to conserve battery life. Power comes from two AAA cells, which are included in the box alongside the calibration weight, a screwdriver, a protection case, and a user guide.
