Starrett DIGI-CHEK II Height Master
No. DHG Series, Ranges up to 85" and 2150 mm
These are the world's fastest and most precise height masters, ideal for those who need the highest degree of accuracy over an extremely long vertical range.
• Can be used in the laboratory or on the shop floor
• Lower inspection cost by saving time - within 10 seconds the tool can be set into position
• The gage block stack is free-standing, so it will adapt to temperature differences in a reasonable time period
• 1" or 25 mm range of adjustment
• Reverse reading block allows readings from the underside of the master gage blocks
• The large, remote digital readout can be placed in the most convenient location and adjusted for best readability
• System can be retrofitted or exchanged for Starrett-Webber Optical Height Gages now in use
• The housing is heavy and extremely stable. It has hardened and lapped three-point bearings

Starrett DIGI-CHEK Height Gages
No. 258, 258 M Series
These gages combine the accuracy of Starrett-Webber Gage Blocks with a precision micrometer head and digital readout.
Readability Features
• Satin chrome scales mounted beside the gage block column for quick reference to the nearest 1" or 25 mm reading
• Digital readout reads on .001" or 0.01 mm and has a range of 1" or 25 mm
• Reads directly from the micrometer head to .0001" or 0.002 mm. The micrometer head (our No. 469) has black figures on the satin chrome thimble. The graduations are staggered for easy counting
• Both the micrometer head and digital readout are mounted on top of the gage, directly in line with the operators' vision
Ease-of-Handling Features
• The micrometer head has a speeder knob for rapid positioning
• Both over and under heights can be checked directly from the gage blocks in a single setting. Because reference surfaces are provided on the top and bottom of each block, adjacent blocks are in the exact same plane. This eliminates the need to add or subtract block thickness.
• Readings can also be taken from either left, center, or right of the gage block column
• Parts can be checked from .100" or 2 mm in height
• The gage block column design permits wringing a 1" block between two blocks in the column. This is convenient for setting and checking other gages such as inside micrometers, end measuring rods, dial bore gages, etc.
Accuracy and Long-Life Features
• Gage is housed in a heavily flanged frame for stability and the base has three-point hardened, ground, and lapped bearing pads, making it virtually tip-proof
• Gage blocks are assembled in a freestanding system that allows the blocks to conform to temperature variations independently of eh frame, thereby reading the same as the work piece
• The highly accurate micrometer spindle is one piece, with the measuring threads ground from eh solid, hardened, and stabilized
• A 10" riser block is available for increased height capacity
