293-187-30 Mitutoyo Digimatic Micrometer

QuantuMike Coolant-proof micrometer The 293-187-30 Digital QuantuMike utilizes a courser spindle thread which feeds the spindle by 2 mm per revolution of the thimble instead of the standard 0.5 mm. The coolant-proof micrometer’s ratchet thimble mechanism provides a constant measuring force on the spindle to ensure accurate, repeatable measurements.

It comes with one year limited manufacturer’s warranty. Shop for 293-187-30 at MRM Metrology and use CAL 293-187-30 when ordering calibration services.
