Mitech Industrial Ultrasonic Angle Beam TR Probes For Longitudinal Waves,selects the superior performance of the piezoelectric material chip made carefully,strong penetrating power,high signal-to-noise ratio,good wear resistance,excellent near surface resolution,scattering noise is small,and medium water,plastic and other low impedance matching effect is very good.The key manufacturing process adopts special equipment and fixtures,which can eliminate the influence of human factors as far as possible.We can provide quality customized solutions to meet the special needs of customers.The interface is mostly lemo-00 (C5) connector (direction is side or top), widely used in coarse grain weld, attenuation material and austenite weld inspection.Using domestic and foreign relevant standard testing equipment and strict calibration block,demanding perfection,quality link can provide with the probe sequence number only corresponding to the measured echo waveform and spectrum graph,all data have traceability,can according to customer requirements to provide certificate from amplitude curve. Consistent with "EN12668-2" relevant standards at domestic and abroad.
