Digital Model Electronic Micrometer Fast Hole Measuring Diameter

Highly precise parts presently used in every aspect of industry including consumer electronics, audio & visual devices, automotive and communication devices are becoming more and more microscopic every year.

As the precision of industrial parts advances, simple structure measuring instruments that anybody can use to measure with high precision and few errors are required.
The answers to these needs are the Air Micrometer and the Electronic Micrometer.

The Air Micrometer is a relative measuring instrument that can measure the dimensions of a piece of work using air flow.
There are different measuring systems including the Flow type, and the Back Pressure type(differential pressure type).
Let us explain the Flow type measuring method(our product name: AM-10F).

After clean air is produced with a compressor and filtered, it is blown out nozzle with its pressure kept constant by a regulator.
When the clearance between the nozzle and the work to be measured changes, the amount of air being blown out the nozzle also changes, causing the height of a float to change.
The movement in position of the float can determine the actual dimensions of the piece of work.
There is an Electronic Micrometer similar to the above-mentioned relative measuring instrument.
It measures dimensions with a contracting type gauge head

This system that electrically magnifies the mechanical and very little variation enables precise measurement with prompt response, differing from an Air Micrometer.
As seen so far, our many years of precision gauge manufacturing techniques are applied in the manufacturing of measuring heads and master gauges that make full use of the characteristics regardless of being an air or Electronic Micrometer.
