Frequently Asked Questions
How do I use a tubular inside micrometer?
Select the appropriate extension rod that best matches the bore size, assemble it to the micrometer head, and then insert the tool into the bore. Gently rotate the ratchet thimble to make contact with the walls, then take the reading from the sleeve and thimble scales.
What is the measuring range of this set?
This tubular inside micrometer set covers measurements from 0 to 150 mm (0 to 6 inches) using interchangeable extension rods, suitable for a wide variety of bore diameters commonly found in marine machinery.
Does the set come with a calibration certificate?
Each micrometer is individually inspected and may be supplied with a manufacturer's calibration report upon request. For most maritime applications, it is recommended to verify calibration before use.
Is this tool suitable for saltwater environments?
While the micrometer is constructed from corrosion-resistant materials, it should be wiped clean and stored in its case after use to prevent rust and maintain accuracy in humid or salt-laden air.
