Ultra Sonic Hardness testers are built with an internal protection circuit to protect the device against interference. Our Service Department has recently acquired a new humidity and temperature-controlled chamber. GENEQ has recently updated its temperature calibration equipment and we are very proud of it.
UCI Portable Hardness Tester w/2kgf Probe
AUH-II can be used in a broad variety of metals with a wide measuring range and high accuracy. The ZSC technology also solves the traditional ultrasonic portable hardness unstable problem because of the environment and human factor. PCE-5000 is a portable hardness tester that uses the ASTM A1038 ultrasonic contact impedance method to measure the hardness of metals and alloys with a minimum thickness of 2 mm / .08 in. Ultrasonic hardness testing is considered nondestructive, as it creates a microscopic indentation only visible when using a high-powered microscope. UCI hardness tester is made with a hand-held probe and host connected by a cable.
This is different than the Brinell and Vickers tests, where the size of the indentation is measured after the indentation process. The Rockwell hardness of the material is based on the difference in the depth of the indenter at two specific times during the testing cycle. The value of hardness is calculated using a formula that was derived to yield a number falling within an arbitrarily defined range of numbers known as a Rockwell hardness scale. ASTM A1038 test method determines comparative hardness values by applying the Ultrasonic Contact Impedance Method on metallic samples.
Ultrasonic hardness testers
ASTM A1038 test method covers the determination of comparative hardness values of metallic elements by applying the Ultrasonic Contact Impedance Method . The UCI hardness tests may be used on large or small components at various locations. Testing of machine parts, weld seams, coatings and hardened parts even at difficult to access locations and at any angle Fast and easy hardness … Our customer McDermott will be using our device on many of there piping systems in there refineries and powerplants to determine the hardness values of all types of metal materials. Automotive parts made of ultra-high strength steels are produced by press hardening in order to obtain high-strength components.
For this method the test indentation size that of the Vickers diamond is not evaluated optically but measured electronically when the corresponding test load is reached. When testing ultrasonic contact impedance hardness testing of corrugated rollers, there is sometimes only a very small area available on the radius of the corrugation for an exact, reproducible hardness test. It is therefore essential to position the hardness test probe very precisely on the head radius of the profile. C. ASTM shall use reasonable efforts to make online access available on a continuous basis.
There have been several studies [14–20] that measured stiffness changes of soft tissues by measuring the frequency shift of resonance signals. To verify the induced frequency shift and the amplitude change of the signal, the equations are simulated with actual values by changing the stiffness in the range of muscle tissue . The UCI hardness test may be used on large or small components at various locations. It can be used to make hardness measurements on positions difficult to access, such as tooth flanks or roots of gears.
