Advantages of Portable Hardness Testers

Hardness testers are devices that are used primarily for testing the hardness of workpieces by applying rapid shock loading. These instruments are designed to measure the force required to penetrate a material, either with a calibrated steel probe or a diamond tip. Hardness testers are used to determine the hardness of steel, aluminum, brass, and other materials.

Hardness testers have taken on a variety of forms over the decades since their invention. Most manufacturers now produce a wide variety of models to suit various applications and needs of users. In general, hardness testers are classified as either impact testers or penetration testers. Impact testers use an impact hammer to generate shock loads while penetration testers must penetrate a workpiece in order for the resulting force to be measured. Both types serve identical functions and have the same basic design components.

 

Portable Hardness Testers

Portable Rockwell hardness tester: Portable Rockwell hardness tester is the commonly used hardness testing equipment in the industries. The machine is a handy piece of equipment. It can be moved around easily and used by a single person. The portable hardness testers are available in different types and specifications, and they can be utilized in various industries, such as engineering, construction, automotive industry, etc.

The portable hardness tester is also available with a computerized digital display with auto-ranging features and data evaluation system at reasonable price. Most engineers prefer this machine as they do not need to use an external computer for data analysis or saving/recording of test results etc.

Metal Hardness & Ultrasonic Testing: A manual hardness tester using a ball-peen hammer would not be suitable for daily use. It can be used just to confirm if the material is really harder or softer than the supplier’s specification. A portable Rockwell hardness tester is much more convenient and can measure the hardness in different areas of a workpiece simultaneously.

Unlike manual devices, it will provide digital reading directly for comparative purposes, which can be easily recorded into a computer or printed out for future reference. The portable metal hardness tester comes with a printout, which is mainly used for recording data automatically if the device is connected to a computer rather than manually writing it down on paper. However, the printed record can be stored for a long time and is easier to read than making notes during the testing process.

A portable hardness tester can also conduct a variety of other testing methods including indentation test, micro-hardness test, splitting tensile test and for rough hardness. Its measuring range can cover a few grains (HRA) to hundreds of Rockwell C (HRc), which reflects different hardness levels.
