Features

• Full Range Set - Covers 0-25mm through 275-300mm in 25mm steps, plus 1-2" and 2-3" imperial sizes
• Ratchet Stop - Delivers consistent, repeatable measuring force on every reading
• Carbide Measuring Faces - Hardened carbide anvil and spindle resist wear for long tool life
• 0.01mm / 0.0001" Graduation - Fine vernier graduation for precise OD measurement
• Supplied Setting Standard - Ships with a setting standard for all ranges above the base size
• Robust Frame - Solid, rigid frame construction minimises flex during measurement

How to Use

• Zero Against the Standard - Check zero on the setting standard (or closed jaws for the 0-25mm model)
• Turn the Ratchet Stop - Always advance the spindle using the ratchet, not the thimble, for consistency
• Read Sleeve + Thimble - Add the sleeve line reading to the thimble scale reading for the final value
