Caliper Gauge

As to internal caliper gauge IM-880 series, the distance between contact points facing outside is firstly set at standard dimension with ring gauge
or micrometer. Then, it is measured by inserting contact point into internal dimension part to be measured after its outer dial of which moves
together with rotated bezel is set at “0”. The displacement of indicator from “0” point of outer dial is to be measured at that time. The value adding
to the read displacement to standard dimension or deducting it from standard dimension is the dimension of internal diameter. This series
attaches spare contact point which cam set accurate dimension corresponding to size of internal dimension. External caliper gauge is opposite,
namely reading the value by holding work piece with 2 contact points facing outside.

Internal Dial Caliper Gauge

These gauges are designed for use in measuring deep internal diameter of bores of castings etc, and for internal reading in fabrications.
Clearance has been provided for use in recessed bores. The convenient retraction lever allows one-hand operation.

Dial Depth Gauge

• Internal caliper gauge to measure internal diameter of cylindrical
workpiece and recessed groove diameter. It can measure groove
diameter of "O" ring by modifying spare contact point.
• Set dimension within ±1mm (indication range 2mm) can be
comparatively measured (880 series) by alternatively using auxiliary
spare contact point in accordance with measured dimension.
• Please set standard dimension within measuring range with
micrometer or ring gauge.
