Tubular Inside Micrometer 50-300mm 0.01mm Grad. Extension Rods: 13, 25

A specialised precision instrument designed to measure large internal dimensions, such as the inside diameter of large bores, cylinders, and other hollow structures. The 'tubular' design refers to the use of lightweight, hollow tubes (or rods) that can be extended and combined to cover a wide range of measurements, making it ideal for measuring large internal dimensions with high accuracy.

• Graduation: 0.01mm
• Travel of micrometer head: 13mm
• Accuracy: (3+n+L/50)µm
  • n is number of rods
  • L is max. measuring length in mm
• Supplied with setting standards
• Carbide measuring faces

Applications

• Large Bore Measurement: Ideal for measuring the internal diameters of large bores and cylinders in industries such as automotive, aerospace, and heavy machinery.
• Quality Control: Widely used in quality control processes to verify that large internal dimensions meet the required specifications.
• Manufacturing: Used in manufacturing environments where precision measurement of large internal components is essential.
