caliper gauge

5Caliper 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 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.

Arm Slide Type Caliper Gauges��Stable and accurate measuring dimension (comparative measurement) is possible for internal and external dimension, as this can well stick to

workpiece with measurement method by sliding movable arm.��Boxy type, easily to hold, lightweight and solid, this is suitable to inspect large volume at work site.��This can be used for various objectives to measure internal gears, internal diameter female screw, plain gear, spline shaft of special key, over

pin diameter of separation shaft and pitch gear thickness.��Contact point is separately produced on demand such as ball type, flat type, knife edge type. Please advise dimension and shape.��As Digital indicator is an option, please select it according to an objective. Because dial indicator can be installed.��This can print out data by connected to Digital mini printer SD-763P (option).
