Portable Hardness Testers

Hardness Testing is a widely used method for determining hardness of materials using test methods such as Vickers, Brinell, Knoop, Rockwell, Shore, Clark and IRHD. Portable hardness testers come in a variety of types with the ability to test most metals, alloys and plastics ranging from soft polymers and rubbers to engineering alloys designed for use in the most arduous conditions or most severe operating environments. In addition, Portable Hardness Testers equipment offers a quick and economical supplement to stationary hardness testing in the modern production process.

What is a Portable Hardness Tester?

A portable hardness tester allows you to test the hardness of a metal without having to transport the metal to a large stationary machine. A portable hardness tester makes testing metals for your customers' orders much easier or for testing metal before using it to create your parts. A portable hardness tester for Rockwell testing is a small hand-held tester with an "impact device" attached that sends the information back to the computer where a mathematical formula determines the hardness of your metal. This is vital because your metals must have a specific hardness value in order to be used for a particular application. Popular portable hardness testers are manufactured by Phase II and Mitutoyo. The most popular and versatile portable hardness tester for Brinell testing is the King portable hardness tester.

What are Hardness Test Blocks?

Hardness test blocks, traceable to the National Institute for Standards and Technology (NIST), are manufactured by a number of American hardness test block manufacturers such as WESTport Corporation. The different hardness test block types are Rockwell, Brinell and Microhardness test blocks (also referred to as to as Knoop and Vickers test blocks). These hardness test blocks help you to measure your metals against a standard. Hardness test blocks are calibrated to a particular hardness value and verify the accuracy of your portable hardness tester or bench model hardness tester. This verifies that your measurements are in compliance with industry standards.

What are Special Taps?

Special taps come in a variety of types such as high speed steel, carbide, cobalt, taper, plug, bottom, fluteless, or spiral flute taps. Special taps are a cutting tool that cuts internal threads and are manufactured in compliance with specifications from ANSI standards (American National Standards Institute). Blank dimensions refer to the steel cylindrical blank from which special taps are manufactured. Special taps may be different from standard tap design criteria as it relates to thread type, size, shape, number of threads per inch and so on.

What is a Durometer?

A Durometer is used to measure the hardness of non-metallic materials, such as rubber, plastic, foam, wood, etc. A durometer works by measuring the depth of an indentation in the material created by a standardized given force. The basic durometer test requires applying the force in a consistent manner, without shock measuring the hardness (depth of the indentation). If a timed hardness is desired, force is applied for the specified time and then calculated. There are several scales of durometer, used for materials with different properties. The two most common durometer scales are the ASTM D2240 type A and type D scales. The A durometer scale is for softer plastics, while the D durometer scale is for harder ones. However, there are a total of 12 durometer scales; types A, B, C, D, DO, E, M, O, OO, OOO, OOO-S, and R. Each scale results in a value between 0 and 100, with higher values indicating a harder material.

Portable Hardness Testers

The experts all have something to say about the economy for the upcoming year. There are as many opinions about what is going to happen as there are people that have these opinions. Many of the experts say the economy is beginning to recover and I am inclined to agree with them. Things are better than they were a year ago and they will continue to see a slow upward progression.

The best way a person can deal with a poor economy is to do everything we can to be prepared. One person cannot control the economy, but they can control their own destiny. The best thing a person can do to prevent financial distress is to live below their means and use the excess income to prepare yourself for times of economic down turn.

It does not necessarily take a recession to put you in a poor financial situation. It is actually times of prosperity that cause the problem. Many people spend money they don't have without thinking about it, by using credit cards and home equity loans. It is the times of recession that make this mindless spending more apparent.

The past several years have been a wake up call to many individuals. The best thing people can do is learn from it and make changes that will help them in the future. Begin by developing a debt management plan that will help you pay off your debt, if you have consumer debt. Before you buy, take time to decide if your purchase is a "need" or a "want" and how essential it is that you have this item.

Once you get a plan in place for debt elimination, begin thinking about building wealth. There is a lot of information about preparing yourself for a financially stable future. Become an expert in wealth building and pick and implement a plan that fits your personality. This is a challenge that may take several years, but it will be well worth it in the end.
