• The one revolution dial indicator (back plunger type) prevents the possibility of reading errors.
• Back plunger type dial indicators are suitable for mounting onto levelling machine tool tables or inspection jigs, and for use in situations where standard dial indicators are difficult to read.
• Mitutoyo's unique shockproof mechanism provides excellent durability and shock resistance.
• Model 2990A-10 provides 0.001 mm graduation.
• The red dead zone in the middle of the dial face is separated from the bezel and doesn't cover the graduations. Therefore, users can always see the range where accuracy is not guaranteed even if the bezel is rotated.
