Maximum Measuring Accuracy
Linear ±0.000040″ (±0.001 mm)
Repeatability <0.000040″ (<0.001 mm)
Gage R & R ≤10% capability when measuring
high tolerance bores. Please contact Dyer with your application.
Used to measure close to the bottom of a bore
Contacts are set towards the bottom of the sleeve to allow the measurement to be close to the bottom of the part
Gage can rest on the bottom of the part or be raise and lowered throughout the length of the bore. Measuring at the top of the part requires a depth stop for added stability
Insertion chamfer makes is easy for gage to enter part
Carbide ball contacts are standard, but other materials are available upon request
Special contact profiles are available: such as wedge, mushroom, and special radius versions

The “h” dimension is the distance from the centerline of the measuring contact to the bottom of the measuring sleeve.
• “h” = 1.5 mm for Ø 3—6 mm
• “h” = 2.5 mm for Ø 6–20 mm
• “h” = 3.5 mm for Ø 20–60 mm
• “h” = 4.0 mm for Ø > 60 mm
• Special “h” dim. are offered on request
• A complete setup includes a measuring sleeve, holder, indicator, and master ring
