Mitutoyo 468-269 Electronic Inside Micrometer 1.6 to 2 in IP65

Product Description

The MITUTOYO 468-269 is a 3-point contact electronic inside micrometer designed for precise internal diameter measurements in the range of 1.6000 to 2.0000 inches. It delivers a resolution of 0.00005 inches and an accuracy of 0.00015 inches, making it suitable for high-tolerance bore measurement work. The titanium nitride finish improves surface hardness and wear resistance. Rated IP65 for dust and water-jet protection, this instrument holds up in shop-floor and machine-tool environments. A ratchet stop thimble provides consistent measuring force, and the large LCD display with 7.5 mm character height allows quick, clear readings. TUV certified to recognized metrology standards.

The MITUTOYO 468-269 is used in precision machining, engine rebuilding, hydraulic cylinder service, and quality-control inspection where accurate bore or internal diameter readings are required. The 3-point contact design self-centers in the bore, reducing the operator influence common with 2-point inside micrometers. It is well suited for production floor use and inspection labs that require data output capability for SPC or part documentation workflows. Batteries are included, and the instrument ships in a protective plastic case ready for immediate use.

Key Features

• Accuracy rated at 0.00015 inches per TUV certification
• IP65 ingress protection resists dust and direct water jets on the shop floor
• 3-point contact head self-centers for repeatable bore measurement
• Ratchet stop thimble delivers consistent, controlled measuring force
• Data output port supports SPC and digital record-keeping integration
• Titanium nitride finish for extended durability and impact resistance

Compatibility

Designed for use as a precision bore measurement instrument in applications requiring internal diameter readings between 1.6000 and 2.0000 inches; compatible with standard data output collection systems that accept digital micrometer input.

Installation Notes

Calibration and use should be performed by a qualified metrologist or machinist familiar with inside micrometer procedures. Allow the instrument and workpiece to stabilize at the same ambient temperature before taking measurements to minimize thermal expansion error. Clean contact points and the bore surface before measuring. Replace the SR44 battery when the low-battery indicator appears to avoid measurement drift.
