Mitutoyo 468-262 Electronic Inside Micrometer IP65

Product Description

The MITUTOYO 468-262 is a 3-point contact electronic inside micrometer designed for precision bore measurement in the 0.3500 to 0.4250 inch range. It delivers a resolution of 0.00005 inches and an accuracy of 0.00010 inches, making it suitable for tight-tolerance work in machining, metrology, and mechanical service environments. The instrument carries an IP65 ingress protection rating, meaning it resists dust and low-pressure water jets during use on shop floors or in field service conditions. A ratchet stop thimble ensures consistent measuring force on every reading. Licensed metrologists, machinists, and precision maintenance technicians are the primary users.

The 468-262 is suited for measuring small bores, holes, and inside diameters where a standard two-point micrometer cannot achieve stable contact. Its three-point contact design self-centers in round bores, reducing operator error and improving repeatability. The large LCD display with 7.5 mm character height makes readings easy to confirm in variable lighting conditions. The built-in data output port allows direct connection to statistical process control systems or Mitutoyo data collection interfaces, supporting quality documentation workflows in manufacturing and inspection settings.

Compatibility

Designed for precision bore measurement applications requiring inside diameter readings in the 0.3500 to 0.4250 inch range, compatible with Mitutoyo data collection systems via the integrated data output port.

Installation Notes

This instrument is a handheld measuring tool, not a permanently installed component. Calibration should be verified before use according to your facility's metrology procedures. Keep the contact points and bore surfaces clean and free of chips or coolant residue before measuring. Do not drop or impact the instrument, as damage to the contact points or internal electronics will affect accuracy.
