Fowler High Precision Fowler's "Ultra-Height" has evolved to bring you the finest digital height gage of its kind in the industry. Design Features: Resolution: .0005" (.01mm). Lock screw: for scribing, transferring, etc. Microfine adjustment screw. Lock screw locks unit before using fine adjustment screw. Sturdy single column beam: hardened, ground and stress relieved. Sealed-in Sylvac electronic scale is unbreakable and not affected by oil, dust, chips, magnetism, shock, etc. Robust base is fully hardened, ground and microlapped to ensure accuracy. Stress-relieved base. The base/scriber design allows direct zero reading from the base over the full range. Base size: length 6", width 3-1?2", height 2-1?2". Carbide-tipped scriber Electronic Specifications: Completely re-engineered measuring sensor, a marked improvement of the already proven Sylvac capacitive measuring system. Incremental floating zero. Deviations are read out directly with no math. Direct inch/metric conversion 2 presetable references Increased measuring, tracking speed of approximately 60"/second. Zero button may be reconfigured as a hold button. If tool is used for SPC, it'll automatically be configured as a data output switch. Large, high contrast LCD display indicates in/mm, hold, and zero functions. Hold feature freezes display for later viewing. Ideal for hard to reach places.
