Air Comparator Gage

An Air Comparator Gage is a type of measuring tool used in the field of metrology for precise measurement and inspection purposes. It is classified under the supply class "Inspection Gages And Precision Layout Tools" and belongs to the supply group "Measuring Tools".

The Air Comparator Gage operates on the principle of comparing the pressure of a reference air source to the pressure of the air being measured. It consists of a pressure regulator, a precision dial gauge, and a set of interchangeable nozzles or orifices.

To use an Air Comparator Gage, the operator connects the reference air source to the regulator and adjusts the pressure to a known value. The air being measured is then connected to the other side of the regulator, and the pressure is compared to the reference pressure using the dial gauge. The difference in pressure indicates the deviation or tolerance of the measured object.

Air Comparator Gages are commonly used in industries such as manufacturing, automotive, aerospace, and quality control. They are particularly useful for measuring small tolerances and ensuring the accuracy of machined parts, components, and assemblies.

Overall, Air Comparator Gages are essential tools for precise measurement and inspection, providing reliable and accurate results in various industrial applications.
