Hardness Tester
Surface hardness is measured using the hardness tester devices available from Dhanbad Instruments. Each hardness tester employs a consistent technique of measurement. Most hardness tester devices measure hardness using either the penetration of a diamond indentor into the material being tested or a calculation based on the force of the rebound after impacting the tested substance. Ultrasonic testing, on the other hand, can properly evaluate material hardness. Each hardness testing method has advantages and will allow for exact material hardness assessment in line with the technical parameters of the hardness testing device.
Metal Hardness Measuring Instrument
There are many different ways to measure the hardness of a metal. The most common method is to use a durometer, which measures the hardness of a material by pressing an indentor into it and then measuring the depth of the indentation. Other methods include the Rockwell hardness test and the Vickers hardness test.
For example, Brinell and Rockwell metal metal hardness measuring procedures, employ a strong force to generate a large depression in the surface of the material being tested. Although the Vickers hardness testing method includes visual measurements, it cannot be used on installed machinery or permanently built parts. Leeb hardness testing machines evaluate hardness using rebound and indirect techniques, although there are considerable differences when translating from Leeb to Brinell, Rockwell, and Vickers hardness scales. Ultrasonic hardness testers detect hardness using the high-accuracy ultrasonic contact impedance (UCI) technique, which leaves a minute indentation on the surface of the substance being tested. However, because of the degree of precision and the largely nondestructive nature of testing provided by an ultrasonic hardness tester, the metal hardness measuring instrument is generally more expensive.
If you are in the market for a hardness tester, you may be wondering if a digital portable hardness tester is the right choice for you. There are many benefits to choosing a digital portable hardness tester, including the fact that they are much more accurate than their analog counterparts.
Digital Portable Hardness Tester
Because of its mobility and ergonomic form, a hardness tester is especially useful in industrial production, quality control, and technical service. There are a number of high-quality, digital and portable hardness tester items in Dhanbad Instruments' comprehensive range of test and measurement equipment for detecting the hardness of practically every substance – from metal, plastic, and rubber to concrete, leather, and beyond. A hardness tester measures hardness in Shore (HS), Rockwell (HRA/HRB/HRC/HRD/HRE/HRF/HRG/HRH/HRK/HRN/HRT), Brinell (HB), Vickers (HV), Leeb (HL), Barcol (HBA), Webster (HW), or MPa (N/mm2) SI units, depending on the type. A 360° dial can be found on an analogue or mechanical hardness tester, whereas an LCD screen is often found on a digital portable hardness tester. Some digital hardness tests include data logging features such as internal memory and a USB connector for data transmission to a computer.
