Peacock Cylinder Gauges (Blind Hole Type) – CG series

Code : CG-01, CG-1, CG-2, CG-3, CG-3C, CG-4, CG-5, CG-6

Cylinder Gauges (Blind Hole Type) ; CG series
If using a CC type cylinder gauge for blind hole bore diameter, its guide plate interrupt the
measurement at a point deeper than “T”, as shown in the figure below.
In such case, the CG type with modified guide plate is suitable for measurement of the
diameter to the point as deep as “t”.
Dial gauge is not furnished and supplied only on request.
Suitable dial gauges are 17Z, 57B (0.01mm) and 15Z, 5F (0.001mm).
