For different applications, six impact device types are available.UCI and Rebound hardness testing with just one instrument! The brand-new Krautkramer MIC 20 combines the two most successfully applied portable hardness testing principles in one instrument. Whether you want to use the UCI principle or the dynamic Rebound testing method – the MIC 20 offers both possibilities.Rebound hardness, also known as dynamic hardness, . Two scales that measures rebound hardness are the Leeb rebound hardness test and Bennett hardness scale. Ultrasonic Contact Impedance (UCI) method determines hardness by measuring the frequency of an oscillating rod. The rod consists of a metal shaft with vibrating element and a pyramid .Equotip 3 Rebound Hardness Tester. The Equotip is a portable hardness tester using the Leeb rebound hardness testing method and offering extended capabilities and unmatched ease of operation. This is the leading rebound style tester in the market due to its unmatched quality. Features: Converts to all common hardness scales, plus can create .
The Leeb hardness testing, otherwise called as Leeb Rebound Hardness Test (LRHT), is considered as one of the four commonly used methods to test the hardness of the metal. It is a type of non-destructive testing used to inspect large sized workpieces weighing above 1 kg. It also measures the coefficient of restitution.
Leeb Rebound Hardness Tester | CIMETRIX Ltd. More than 40 years as a recognised hardness testing method, ASME, JIS, ISO, DIN, GOST etc.. The Leeb rebound hardness test method was developed in 1975 by Leeb and Brandestini to provide a portable hardness test for metals. It was developed as an alternative to the unwieldy and sometimes intricate . This chapter presents different types of hardness test method, and calibration of testing machines (both direct and indirect method). Conventional static hardness methods (Brinell, Rockwell and Vickers) and dynamic Leeb rebound hardness with corresponding uncertainty calculation is discussed in this chapter.
UCI method and dynamic rebound hardness testing. The decision as to which method is used mainly de-pends on the test task. Fig. 1: Hardness testing with a UCI instrument on the tooth flanks of a pinion shaft. Fig. 2: Hardness testing with a rebound tester on the drive wheel of a large hydraulic digger. 5.1 Hardness of a material is a poorly defined term that may have many meanings depending on the type of test performed and the expectations of the person involved. The Leeb hardness test is of the dynamic or rebound type, which primarily depends both on the plastic and on the elastic properties of the material being tested.Leeb Type Dynamic/Rebound Portable Hardness Tester. More Details >> Leeb Type Dynamic/Rebound Probes & AccessoriesThe hardness measurements are made by using the dynamic rebound testing method according to Leeb. Leeb hardness testing was invented in 1975 in Switzerland and has become one of the most popular portable testing .
Two such testers are found on the market today. They are the Equotip dynamic rebound hardness tester and the Microdur ultrasonic hardness tester. The Equotip is a portable hardness tester that can take measurements in any direction on all types of surfaces, including flat, convex, concave, spheroidal, and even in grooves.The hardness tester functions by releasing a small impact device on to the metal testing surface by means of a spring mechanism. The gauge's dynamic measuring procedure works by calculating the difference between the impact velocity and the rebound velocity of impact device. The TH-170 can be used on a whole variety of metals.
The IMPACT TH-1100 is a small, integrated digital hardness tester which operates according to the dynamic rebound method (standardized according to ASTM A956). The compact design allows easy on-site hardness testing on solid, components that are difficult to transport, or to be used on positions difficult to access by other hardness testers. The Equotip hardness tester (EHT) is a portable and non-destructive instrument used mainly for the dynamic rebound hardness testing of metals. Although various versions of the ‘single impacts’ and ‘repeated impacts’ testing procedures have been employed by different authors for different applications, it is not yet known whether a particular testing procedure is .Hardness testing using the MIC 20 in combination with the test support MIC 227 and a UCI probe in the heat-affected zone (HAZ) of a weld.

The methods and instruments available can be confusing and the selection of the instrument is very important. While every portable hardness tester we offer is good for some applications, they are in all honesty, lousy at others.A general purpose impact probe, suitable for the majority of hardness measurements with a wide measuring range. C Type A smaller indentation and covers a slightly wider hardness range compared to Type D, but requires a better surface finish. DC Type Used in confined spaces like holes, cylinders, or inside of assembled machines. G Type
Rebound hardness has more to do with elastic hardness than plastic hardness. The material absorbs the energy on impact and returns it to the indenter. An indenter is a reference material used for hardness testing. Dynamic hardness is usually measured by dropping a diamond-tipped hammer on the test piece and recording the hammer’s bounce .
