China wholesale Vernier Measurement – High Precision Double Column Dial Height Gauge – Tool Bees

This dial height gauge has a measurement range of 0” – 24”/0mm-600mm, and is precise to 0.001”, with + or – 0.002” of accuracy.

The height gauge has dual, resettable counters that additionally measure up and down distance changes, in 0.01” increments. A hand-operated feed wheel raises and lowers the gauge on the parallel beams, for ease of measurement. The scriber is used to mark a position on a workpiece, carbide-tipped for hardness and to help prolong life, and is held to the gauge by a screw clamp for fastening ease.

Height gauges, also called gages, are precision measuring instruments that travel on a vertical column to measure and/or mark the vertical distance from the base of an object in fine units.

The vertical position of the gauge and its attached pointer is changed by turning a calibrated screw, or one or more feed wheels. Recorded rotations are read from a scale, a dial, counters, and/or an electronic display.

A screw clamp holds the pointer to the gauge.

The pointer is typically sharpened to act as a scriber and can be used to mark a position on a workpiece by scratching its surface. On compatible units, the scriber may be replaced by an electronic touch-signal probe.

Height gauges are typically used in manufacturing, machining, and mechanical engineering.
