• Mitutoyo’s Absolute Solar Digimatic Caliper retains its origin point indefinitely.
  • At 60 Lux and above the ABSOLUTE solar caliper is ready to start measurement. No more repeated zero setting caused by a shortage of light.
  • An ABSOLUTE scale is incorporated so that zero setting is not required at each power ON. No danger of overspeed errors.
  • Slider operation is smooth and comfortable.
  • Allows step measurement.
  • Allows integration into statistical process control and measurement systems for models with measurement data output connector. Refer to page A-3.
