The Digi-Chek No. 258 Series Height Masters combines the accuracy of Starrett-Webber Gage Blocks with a precision micrometer head and digital readout display. Highly accurate, stable, and easy-to-read, Digi-Check Height Masters provide an ideal reference setting for checking bore gages, inside micrometers, end measuring rods and other gages, and height measurement of parts.
Featuring the rigid and high precision Starrett design that QC inspectors, toolmakers, and machinists have relied on for years, the Digi-Chek Height Masters have a large, easy-to-read electronic digital display providing instant readout to .0001 in. or 0.001 mm. In addition, graduated satin chrome finished precision micrometer head with speeder knob for fast positioning, provides staggered graduations reading to .0001 in. or 0.002 mm. Both the micrometer head and digital readout are directly in line with the operator’s vision.
The Digi-Chek gage’s housing within a heavily flanged frame and base featuring three-point hardened, ground, and lapped bearing pads, contributes to exceptional accuracy of +/- .0002 in. (+/- .005 mm) and makes the gage highly stable. Gage blocks are assembled in a free-standing system isolated from the frame, allowing the blocks to conform to the workpiece temperature. Accuracy is further enhanced via a one-piece micrometer spindle with hardened and stabilized measuring threads.
Both over and under heights on Digi-Chek Height Masters can be checked directly from the gage blocks in a single setting, and with reference surfaces on the top and bottom of each block, adjacent blocks are in the same plane. Readings can also be taken from either left, center, or right of the gage block column. The column design also permits wringing a 1-in. block between two blocks in the column—convenient for setting and checking other gages.
Starrett Digi-Check No. 258 Height Masters are offered in three ranges: .100 to 12.100 in., .100 to 18.100 in., or.100 to 24.100 in.. Metric models are also offered in three ranges: 2 to 302, 2 to 452, or 2 to 602mm. Gauges are furnished in finished, fitted wood cases.
