Types of Contour Gauges
Physical Contour Gauges
Serrated Contour Gauges
Serrated contour gauges, also known as profile gauges, are a type of
physical contour gauge traditionally used in various trade industries.
The term “serrated” originates from the structure of the tool, which is
primarily composed of a series of thin, metal strips or pins organized
in a parallel sequence. These strips, somewhat appearing like a row of
serrated teeth in appearance, offer the gauge its ability to produce
exceptionally precise profiling measurements.
One of the primary aspects making serrated contour gauges popular is
their simple yet effective design. They are typically constructed with
tough, durable materials like stainless steel or plastic, engineered to
withstand hands-on usage while maintaining a high degree of accuracy.
The serrations are designed to minutely adjust to the shape of the item
being measured, thereby creating an exact contour duplication.
Most serrated contour gauges accommodate the measure of objects that
are up to several inches in length, depending on the model’s size. You
will find them in a variety of lengths, suiting different applications
and professional needs. What remains consistent across all varieties is
their simplicity to operate, making them a reliable tool for even the

Magnetic Contour Gauges
Magnetic contour gauges are a subset of physical contour gauges that
make use of magnetic adhesion to create an impression. Similar to
serrated contour gauges, they also have a set of pins or teeth. However,
in this case, the teeth are magnetized.
Their implementation revolves around the attraction to ferrous
metals. When you press the gauge against a surface, the magnetic pins
stick to the metal object. In this process, it shapes itself to the
exact outline of the object, which can then be traced or transferred to
the material one aims to cut or shape.
Magnetic contour gauges stand out because of their ability to capture
contours on metal surfaces where normal contour gauges may slide off.
This characteristic makes them particularly useful for complex
automotive bodywork, intricate metal fabrication, and other tasks where
non-magnetic gauges may come up short.
Like other physical contour gauges, magnetic contour gauges do not

How does a Contour Gauge
work?
Explaining
the working principle of physical contour gauges
Physical contour gauges function by taking advantage of their
multitude of tightly-packed, flexible, and adjustable vertical metal or
plastic slats. These slats are designed to conform to and retain the
shape of any surface placed against them, making it possible to capture
even complex profiles with ease.
To utilize a physical contour gauge, you need to press it against the
target surface. The slats slide perpendicular to their length, creating
a proportional and negative reproduction of the contour of the object.
Once the gauge is removed, the one-to-one correspondence structure
provides a precise profile of the original surface condition. This
output can then be utilized as a reference while cutting, designing, or
shaping materials to match that profile.
It is crucial to mention that the accuracy of a contour gauge can
often depend on factors such as the individual slat width, with narrower
slats being able to deliver a more precise replication of the surface
contour. Similarly, the rigidity of the slats also plays a role as
excessively flexible slats may inadvertently distort the captured
profile. Therefore, while using a physical contour gauge, it is
important to handle it with care to ensure accurate readings.

gauge. When pressed against a surface, these sensors track and adapt to
the exact shape and contour of the object, thereby forming an accurate
replica of the surface.
A standout feature of digital contour gauges is the integrated LCD
screen. After obtaining the shape, the recorded data is fed to the
digital display that visually presents the captured contour. Then, the
digitized profile can be stored for future reference or transferred to
another device for further processing or analysis via a USB
connection.
The level of accuracy offered by a digital contour gauge is much
higher than a physical contour gauge. Errors are minimized as manual
assessment is replaced by sound digital technology. Its ability to
