Dial Indicators
• Long stroke dial indicators with measuring range of 20 mm or more have a ø57 mm bezel. • The indicator is highly durable thanks to its oil- and water-tight design, quenched hardened stainless-steel, carbide contact point, and a grand gear made of wear- and deformation- resistant material. • Application of an anti-reflective and hard surface coating improves scale visibility along with scratch and chemical resistance. • The lifting lever (optional) cannot be used with models that are water-proof or which have a measurement range of 30 mm.
