Elastic Modulus Measuring Device(UMS-H／R)●●●Parameters including young'smodulus and the poisson ratio
are measured at the same time.
Easy connection to PC via USB
Ultrasonic flaw detection
available with standard pulser/
receiver equipped.

Elastic modulus is physical property value that shows resistant to deform, which is theratio of stress and strain generated when external force is given to a elastic body. Elasticmodulus includes young’s modulus, poisson ration, rigidity modulus, bulk modulus andothers.
These can be calculated with difference of longitudinal and horizontal wave velocity(density and thickness required). Probes required for both longitudinal and horizontal
wave measurement.

Property values unique to each material are calculated by measuring reflection time
when ultrasonic wave is transmitted into a test piece. With a flat space to attach theprobe, not only a test piece but also a product can be measured. Measurement values
are longitudinal wave velocity, horizontal wave velocity, young’s modulus, rigid modulus,
bulk modulus, compressive elastic modulus, poisson ratio, lamé parameters, anisotropyof the sound velocity, Debye temperature and others.
Tips for how to use
Click to designate the 1st and 2nd bottom echo of aworkpiece for both longitudinal and horizontal
wave, then obtain each ultrasonic velocity respectively, and finally various elastic modulus are automatically calculated of which values are listed below area.

* USM-H： for High temperature /USM-R; for RoomtemperatureSpecial options including heating furnace are needed
for high temperature measurement.
* Refer to reverse page for specifications of Standard
Pulser/Receiver.

Ultrasonic Pulser-Receiver,Material Surface Sound Diagnosis Device
Ultrasonic Pulser-Receiver GNES-1001 comes withthe software for Material Surface Sound Diagnosis
Utilizing SH wave pulse which is generated in parallel withthe surface, property change near surface layer of the material is measured and analyzed non-destructively. Making calibration curve of the amount of surface material change ofmetal/ceramic/polymer and others together with specificwaveform parameters, evaluation of material property can bedone, such as hardness, fatigue, membrane thickness, deterioration, crack and others.
Bundled Software
Elastic Modulus Measuring Device is equipped with Pulser/Receiver
having the software of Material Surface Sound Diagnosis.
