There are two classifications calibrated and directly traceable to (N.I.S.T.). Standard Black Gages are guaranteed to be better than ≤ 4µm (.00016″) accuracy. Precision Gold Gages are guaranteed better than ≤ 2µm (.00008”) accuracy.


  • Adjustable multi-position top arm yoke assembly offers a variety of clamping pressures and positions to accommodate a range of part diameter sizes.
  • All standard indicator carriers have fine adjustment screws that provide accurate indicator probe positioning, zeroing and provide smooth indicator movement to increase measuring performance and accuracy.
  • All gages come standard with a manual drive timing belt pulleys system that provides a constant smooth part rotation when inspecting. (Optional) 110/220 volts AC/DC fixed speed or variable speed motorized drive systems are available.
  • All carriers offer a variety of positions that move along the Z-axis of the carrier rod assembly. The carrier tilts 90 degrees to facilitate easy loading and unloading of parts.
