• The one revolution dial indicator with improved water resistance prevents the possibility of reading errors.
• Mitutoyo’s unique shock-proof mechanism is incorporated, providing improved resistance to shock due to sudden spindle retraction caused by impact.
• It is highly durable thanks to a hardened stainless-steel stem and spindle, carbide probe, and a large gear made of wear- and deformation-resistant materials.
• Application of an anti-reflective and hard surface coating improves scale visibility along with scratch and chemical resistance.
• 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.
