Mahr Federal offers the next generation of its µMaxµm line of digital indicators. The enhanced µMaxum II line offers a range of features, including dynamic max., min. and TIR; two-point difference measurement; multiplier factor for ratio measurements; indicator serial number identification; resolution to 10 microinches; selectable continuous output; and increased battery life.
Versatility enhancements include resolution that is selectable in increments ranging from 0.001" to 0.00001" (0.02 to 0.0002 mm) to accommodate differing application requirements.
Two-point difference measurement enables comparison of different readings or calculation of measured values. The addition of Multiple Factors for ratio measurements enables chordal-type measurements, which are used for making ID/OD measurements using a V‑plate or for gage fixtures using lever-type, non-direct contacts.
For gage management, data can be output with indicator serial number. This can improve ISO tracking, in which a number of indicators are networked on a production line, or help identify which gages need to be pulled for recalibration.
Other features include normal/reverse sensing; a high-resolution digital output with analog bar graph or go/no-go display; selectable MarConnect data output via USB, OPTO ES232C, or Digimatic; application of unilateral tolerances; and an auto power-down feature, which conserves power and helps ensure increased battery life.
Two digital indicator models are available, the µMaxum II and the µMaxum II XL, which provides longer measuring ranges.
