Mitutoyo Digital Micrometer QuantuMike IP65 Inch/Metric 50-75mm (2-3") 293-187-30

• Faster measurement is achieved by using a coarser thread which feeds the spindle by 2 mm per thimble rotation.
• Extraordinary battery life of 2,4 years
• Outstanding accuracy
• Ratched thimble mechanism ensures easy single-handed or stand operation.
• Excellent resistance against water and dust (IP65 protection level) enables this micrometer to be used in machining situations that include splashing coolant fluid.

The QuantuMike brand of micrometer, provides users with an excellent measuring experience with higher speed, quality and stability than ever before owing to the integration of sophisticated manufacturing and processing technologies.

Faster measurement is achieved by using a finer thread which feeds the spindle by 2mm per revolution of the thimble instead of the standard 0.5mm. This increase of spindle feed has been made possible thanks to new high precision thread-cutting and test techniques. Trials show that a reduction in positioning times of 60% and measuring times of 35%* can be obtained, compared with a conventional micrometer.

The ratchet thimble mechanism helps ensure repeatable results by transmitting microvibrations along the spindle to the contact face to provide a constant measuring force and encourage good contact with the workpiece. The ratchet works from the thimble as well as the speeder so it is always easy to use - even when making measurements one-handed. The sound of the ratchet provides the user with a sense of confidence and the speeder enables the rapid spindle feed needed when measuring widely different dimensions.

QuantuMike is equipped with a function lock feature to prevent the origin point being moved by mistake during measurement.

A graduated scale is provided on the sleeve for use with a reference mark on the thimble so that every millimetre displacement can be checked to provide extra confidence.

A statistical process control system and a measurement network system can be established to share information regarding quality with a model equipped with the data output function.

Excellent resistance against oil, water and dust enables this product to be used in machining situations that include splashing coolant fluid.
