Mahr Federal has introduced a new long range indicator calibrator, the OPTIMAR 25. A precision benchtop instrument, the OPTIMAR 25 can be used for the calibration of a wide variety of precision measuring instruments. Accurate to ±10 µin. (±0.3 µm) over its full 0 – 1 in. (25 mm) range, the OPTIMAR 25 Calibrator is capable of measuring to many National Standards, and comes with a large MarCheck LCD monochrome digital display with background illumination and clearly readable 13 mm/0.512″ high digits.

OPTIMAR 25 measures dial and digital indicators in the preferred upright position. Using a precise digital encoder, the OPTIMAR 25 measures directly in line with the instrument, with no backlash and a smooth operation. OPTIMAR 25 performs high precision calibration on a full range of measuring instruments, including dial and digital indicators; dial and digital comparators; dial and digital test indicators; electronic probes and gage heads; Air Probes® and jet probes; and any other devices that magnify the linear displacement of a contact point or measuring spindle.
