Comparison Gauges

Comparison gauges are a category of measuring instruments used in metrology as well as in setup and layout applications. They are designed to compare the dimensions or characteristics of objects being measured to known reference standards or other objects with known dimensions. This comparison allows for the determination of the sizes, shapes, or attributes of the objects under examination with a high degree of accuracy. They find extensive use in manufacturing, quality control, engineering, and scientific research to ensure that products adhere to specified standards and tolerances. These gauges are valued for their ability to deliver precise and reliable measurements by relying on comparisons to established standards or known dimensions, thereby guaranteeing accuracy and consistency across various industries and applications.

Feeler Gauge

Feeler Gauge
A feeler gauge is a precision measuring tool commonly used in mechanical and automotive applications. It consists of a set of thin, flat, and flexible metal blades, each with a known and precisely measured thickness. These blades are often notched or marked with their respective thickness values. Feeler gauges are employed to measure small gaps,...

Go-No Go Gauge

Go-No Go Gauge
A go-no go gauge, also known as a no-go/go gauge, is a specialized type of gauge used in manufacturing and quality control to quickly and accurately determine whether a manufactured part or product meets the specified tolerances and dimensional requirements. The "go" side of the gauge consists of a set of features, such as holes,...

Center Gauge

Center Gauge
a center gauge is a measuring tool used in metalworking and woodworking to determine the angle of the points on a lathe or other tools. A center gauge being used to verify the angle of a threading tool. Center gauges can also be used to measure the angles of other tools and components, such as...

Surface Finish Comparator

Surface Finish Comparator
A surface finish comparator is a visual inspection tool used in manufacturing and quality control to assess and compare the surface texture or finish of a workpiece to a set of standard samples. This tool helps operators and inspectors determine the degree of smoothness or roughness of a surface, ensuring it meets specified requirements and...

Optical Comparator (Profile Projector)

Optical Comparator (Profile Projector)
An optical comparator, also known as a profile projector, is a precision measurement tool widely used in manufacturing and quality control. It projects the silhouette or profile of an object onto a screen, allowing operators to inspect and measure its dimensions with high accuracy. The device works by shining a light on the object, usually...

Radius Gauge

Radius Gauge
A radius gauge is a measuring tool used to determine and verify the radii or curved profiles of objects, typically in manufacturing, engineering, and woodworking applications. It is designed to assist in measuring and checking the radius of curved or rounded edges and surfaces accurately. The typical design of a radius gauge consists of a...

Thread Pitch Gauge

Thread Pitch Gauge
A thread pitch gauge is a measuring tool used to determine the pitch or the distance between adjacent threads on a threaded object, such as screws, bolts, or nuts. It is a valuable instrument in various industries, including manufacturing, automotive, and construction, where precise thread measurements are crucial for ensuring proper fits and functionality. The...

Optical Flat

Optical Flat
An optical flat is a precision tool made from high-quality glass or quartz with surfaces that are polished to an extremely high degree of flatness. It is primarily used to test the flatness of other surfaces through the process of optical interference. The principle behind an optical flat is based on the interference patterns that...
