The Mitutoyo mechanical extension rod type tubular inside micrometer offers the ability to measure a wide range of inside dimensions with exact precision.
Features & Benefits
The Mitutoyo mechanical tubular inside micrometer includes a set of solid extension rods to measure a diversified range of inner dimensions of cylinders, rings and parallel surfaces with high accuracy. Slow head travel provides fine measurement position, while a locking clamp holds measurements in place for easier reading. The extension rods have knurled collars for easy, secure installation and removal.
- Available in Metric and Inch sets
- Optional setting rings are available
- Solid extension rod allows for measuring various dimensions with reliability and durability
- Some models are available with carbide-tipped faces for better accuracy and wear resistance
- Vernier scale on the sleeve offers exact measurements
- Satin chrome finish on the sleeve and laser etched scale on thimble for easier reading
- Supplied in fitted plastic case; the 1500mm / 60″ model comes in a wooden case
