Mitutoyo 468-266 Electronic Inside Micrometer IP65

Product Description

The MITUTOYO 468-266 is a three-point electronic inside micrometer designed for precision internal diameter measurement in the range of 0.8000 to 1.0000 inches. It delivers a resolution of 0.00005 inches and an accuracy of 0.00015 inches, making it suitable for high-tolerance bore and hole inspection work. The instrument carries an IP65 ingress protection rating, providing resistance to dust and water spray during shop-floor use. A large LCD display with 7.5 mm character height allows fast, confident readings in demanding lighting conditions. Licensed metrology professionals, machinists, and quality technicians are the primary installers and operators of this instrument.

The 468-266 is used in precision machining, manufacturing quality control, and inspection environments where accurate internal measurements of bores, holes, and cylindrical features are required. Its three-point contact design provides self-centering capability, which improves repeatability in production and inspection workflows. The ratchet stop thimble ensures consistent measuring force across repeated measurements. Data output capability allows integration with statistical process control (SPC) systems and data loggers for documented quality programs. This instrument is appropriate for both light manufacturing and high-precision inspection applications.

Installation Notes

This instrument is intended for use by trained metrology technicians, machinists, or quality control personnel. Before use, ensure the instrument is calibrated and zeroed according to the manufacturer's procedure using an appropriate setting ring gauge. Keep the instrument clean and dry between uses; while IP65-rated, it should not be submerged. Store in the included plastic case when not in use to protect the contact points and electronic components.
