The Mitutoyo mechanical extension pipe tubular inside micrometer offers the ability to measure a wide range of inside dimensions with exact precision.
Series 139
Mechanical Tubular Inside Micrometers Extension Pipe Type
Features & Benefits
The Mitutoyo mechanical tubular inside micrometer includes a set of hollow extension pipes to measure a diversified range of inner dimensions of cylinders, rings and parallel surfaces with high accuracy. The extension pipes are lighter and more cost effective than extension rods. Slow head travel helps provide fine measurement position, while a locking clamp holds measurements in place for easier reading. The extension pipes 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
- Vernier scale on the sleeve permits exact measurements
- Satin chrome finish on the sleeve and laser etched scale on thimble for easier reading
- Supplied in fitted wooden case; the 500mm / 20″ model comes in a plastic case
