Digital Internal Micrometers or sometimes referred to as Digital Inside Micrometers are essentially the same as Mechanical or Analog Inside Micrometers. The key difference is how the user reads and interprets the measurement. With digital internal measuring tools the distance is displaying instantly on a screen, usually an LCD screen (Liquid Crystal Display). Electronic Internal Micrometers are much quicker to use than their manual counterparts. Similar to mechanical versions, some models are provided with an ultra-precision calibration ring gauge. How to calibrate your internal digital micrometer is covered in the instructions that come with your unit. Industrial models often feature a 3 point design and are available both in the digital format with waterproofing. Like the Dasqua professional ranges of electronic internal micrometer, the top of the range models features both an incremental and absolute function.
