Calipers are precision metrology tools designed to measure dimensions with exceptional accuracy, often down to 0.02mm. These essential measurement tools come equipped with jaws designed for internal and external measurements, enabling engineers to measure a variety of geometries.
The tool’s design typically includes a sliding scale (either vernier, digital or dial), which provides easy-to-read results. Calipers play a vital role in ensuring components fit together seamlessly in precision engineering applications. Whether you're working with a complex assembly or a single part, caliper measuring tools are indispensable for achieving exact tolerances.
Calipers operate by positioning and extending their jaws around or within an object and then reading the measurement displayed on the scale. Understanding how to use a caliper is key for precision measurements.
For example, in aerospace engineering, specific calipers for measuring diameters can ensure that a critical bolt aligns precisely with its counterpart thread.
In the medical device industry, measuring caliper tools are used to verify the dimensions of surgical instruments, where even the slightest deviation can impact performance. Additionally, the depth caliper rod feature is particularly valuable for checking recesses or holes, such as those found in automotive engine blocks or electronic enclosures.
With their versatility, calipers are a staple in any engineer's toolkit suited to any scenario requiring reliable dimensional verification.
Accu’s types of calipers on offer are machined from premium materials such as stainless steel and hard plastic, tailored to specific applications.
Stainless steel calipers are robust, corrosion-resistant and ideal for demanding environments like manufacturing plants or laboratories.
Hard plastic calipers, on the other hand, offer lightweight handling and non-conductive properties, making them an excellent choice for electrical applications or environments requiring delicate measurements.
For added durability, optional carbide-tipped jaws provide enhanced wear resistance, while ceramic-tipped jaws prevent scratching delicate surfaces. Lastly, select IP67-rated calipers offer additional protection against dust and water, making them suitable for harsh operating conditions.
At Accu, our selection of calipers is available in a wide range of sizes to suit diverse applications. Standard measuring lengths range from 0-75mm to 0-150mm, with accuracy resolutions varying from a precise +/- 0.02mm to +/- 0.10mm for accurate measurements.
Scale options include vernier scale calipers for traditional manual readings, digital displays for effortless data display and dial calipers for users who prefer the analogue type of measuring.
A: Vernier calipers use a manual sliding scale and don’t need batteries, making them reliable in any setting. Dial calipers have a mechanical dial for easier analogue readings. Digital calipers show measurements on a screen and often include extra features like data storage, ideal for modern applications.
A: Our selection of calipers provides accuracy ranging from +/- 0.02mm to +/- 0.10mm, depending on the model and material.
A: Yes, for depth measurements, extend the caliper’s depth rod (located at the back of the sliding scale) into the hole, recess or slot you want to measure. Ensure the base of the caliper is flush with the surface for an accurate reading.
