Standard Test Method for Portable Hardness Testing by the Ultrasonic Contact Impedance Method
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.
SU-300H Manual Ultrasonic Hardness Tester
Extremely versatile, with many options and configurations to handle all types of hardness tester applications. There are two basic methods of portable hardness testing that is accepted in the field today. The Equotip 550 UCI is a flexible UCI hardness tester for fine-grained material with any shape and heat-treated surfaces. The Equotip 550 features a rugged touchscreen with enhanced software features and analysis functions.
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 the hardness 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.
This model is specially designed to measure Ethyl Alcohol % used as a sanitizer. Simple Calibration——Save 20 groups calibration data for invoking, improve calibration efficiency. An immunological method for quantization of Hevea Natural Rubber proteins using rabbit anti-HNRL serum.
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.
AUH-II can be used in a broad variety of metals with a wide measuring range and high accuracy. vision measurement systems manufacturers 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.
