• 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.

* 2050A-60 and 2050AB-60 are water-proof types that use a rubber bellows to cover the spindle.
Note that the outer diameter of the bellows (ø9.5) is larger than that of the stem (ø8).
Note: Completed products inspection is performed in the vertical orientation (contact point downward) and the stated accuracy is guaranteed.
