MITUTOYO-SERIES 2 – STANDARD ONE REVOLUTION TYPE FOR ERROR-FREE READING, WATERPROOF TYPE-DIAL INDICATORS

Mitutoyo’s unique shock-proof mechanism is incorporated, providing improved resistance to shock due to sudden spindle retraction caused by impact. This series has been developed to eliminate the possibility of reading errors due to miscounting multiple revolutions. The dead zone in red indicates “accuracy not guaranteed”. One revolution type Back plunger dial gages are also available.
