Dial Comparators by Starrett
No. 653 Series with cast iron base, inch and mm reading
No. 653G Series with granite base, inch and mm reading
These bench-type comparator gages are ruggedly built for in-process and final inspection work.
The dial indicator can be adjusted vertically and locked in any position. A sliding ring with locking screw below the beam permits swinging the indicator to either side. The ring also acts as a safety device, preventing the beam from accidentally
dropping. There is a fine adjustment on the beam for final indicator setting.
The hand lifting lever on the indicator raises the spindle and releases it to contact the work. A left hand lever is furnished unless specified otherwise.
Both gages have a maximum vertical capacity of 9-1/4" (235mm) and a throat depth of 5" (125mm) and a vertical indicator fine adjustment of up to 1/2" (12.7mm). Post diameter is 1-1/2".
No. 653 Series have a ribbed, precision ground cast iron base measuring approximately 8" x 9" (200 x 225mm).
No. 653G Series have a Starrett Grade A, Crystal Pink Granite base, measuring 8" x 12" x 2" (200 x 300 x 50mm). Base is finished to an overall tolerance of .0001" (0.0025mm). |
