Features: Range: 0-12?/0-300mm Resolution: .00005?/0.001mm Accuracy: .00005" Measurement data output is available with a water-resistant connection cable Frame is coated with an anti-slip finish for improved grip during use Twice as long battery life than previous models improves throughput and efficiency Auto power ON/OFF function saves battery life and allows for easier use Includes a standard bar except for the 0-1?/0-25mm model Some models include a Mitutoyo Certificate of Inspection* Supplied in a plastic, fitted case IP65 protection permits use in environments exposed to cutting oil, dust, etc.** NOTE: *It is not the type used to obtain calibration certificates. **Anti-corrosion treatment is required after use The Mitutoyo 0-1" 0-25.4mm 0.00005" Coolant Proof IP65 Ratchet Thimble Electronic Digimatic Micrometer produces highly accurate, repeatable measurements even when exposed to liquids and dirt. The Mitutoyo IP65 rated coolant-proof micrometer?s ratchet stop thimble mechanism provides a constant measuring force on the spindle to ensure accurate, repeatable measurements. The combination of the ratchet thimble and speeder enables a rapid spindle feed when measuring widely different dimensions, as well as, easier one-handed measurements.
