Air gaging is a powerful metrology method and first started ensuring quality in the late 1910s. Early versions of such systems were regulated by bubbling air via a level of water within a cylinder, in which air was also passed. The technique utilizes compressed air to measure changes in flow rates and pressure. Oftentimes, air gages are employed in tests where the distances between a workpiece and the precision orifices needed to be measured.

Air gages have the ability to measure small tolerances because of the reliability and magnification they can provide. A resolution as small as 0.00002 inch can be achieved! If you need to measure extremely thin-walled parts for soft materials, air gaging is the noncontact solution you can count on. If you are looking for an air column amplifier, you should consider the Mahr Federal S1840 Air Column Amplifier. Let’s find out more about this amazing product in this product spotlight!

Hardness is not an elementary physical property. It is more of a characteristic of a material. Hardness is defined as an object’s ability to resist indentation. Its hardness is then measured by the irreversible depth of the indentation. When utilizing a load and a certain indenter, one usually looks out for the size of the indentation. The smaller the indentation, the harder that part will be.

With that in mind, hardness testing is used for two general characterizations, which are functionality and material characteristics. You can use hardness testing for predicting tensile strength, testing wear resistance, testing resistance to impact, testing hardenability, and more. Before a test is conducted, scale, thickness, sample size, material, etc., are some of the factors that will be considered prior to selecting the hardness testing method. In this product spotlight, you will find out more about an excellent hardness testing tool that can make this task easier. Introducing the Phase II PHT-5100 Digital Barcol Impressor Hardness Tester.

If you can’t measure it, how can you make it? When it comes to validation and inspection, this is something you need to keep in mind. Today, industry specialists need to measure contour lines. These lines refer to edges and lines that bound or define an object or shape. Stylus method has come of age and is now used to evaluate and detect profiles, as well as accurately determining the contour geometry. If you are looking to get a precision contour measurement system for your shop, you can never go wrong with Mahr MarSurf XC 20. Let’s find out more about it in this product spotlight!

Vernier calipers are measuring instruments required for precise reading of machine parts or fittings. Routine care and maintenance is very important to maintain the consistency and functionality of a vernier caliper. Along with keeping it in a properly allocated space, there are a few maintenance steps one must take to keep your vernier caliper from malfunctioning.

If you work in some industry, which deals in small fittings or parts, you must know the importance of an extremely precise measurement. For such a purpose, we require an instrument like micrometer to get exact readings, which is important for accurate end results.

A durometer is a device used for testing the hardness of rubber and various plastics. A durometer is basically used to measure a material’s indentation depth produced by a given force on a standardized pressure foot. The depth depends on the duration of the test, the shape of the pressure foot, its viscoelastic properties and the hardness of the material. A basic test requires the application of force in a consistent manner to measure the depth of the indentation without shock. When a timed hardness is reached, force is usually applied for a required amount of time and then read.
