Profile: Mitech Instrument Co., Ltd. is a manufacturer of non-destructive testing instruments. Our main products are ultrasonic digital flaw detectors, portable metal hardness testers, and ultrasonic thickness gauges. Our instruments are widely used in power, petroleum, chemical and pressure vessel manufacturing industries. Our MFD350 portable ultrasonic flaw detector with hi-resolution color TFT LCD display is an advanced digital ultrasonic flaw detector featuring a multi-color TFT. It combines powerful flaw detection & measurement capabilities, extensive data storage, and the ability to transfer detailed inspection data to the PC via its high-speed USB port. The instrument incorporates many advanced signal processing features including a 10MHz RF bandwidth to permit the testing of thin materials and narrowband filters to improve signal to noise in high gain applications along with spike pulsar to optimize penetration on thick or highly attenuating materials. The instrument can be widely used for locating & sizing hidden cracks, voids, disbands, and similar discontinuities in welds, forgings, billets, axles, shafts, tanks, pressure vessels, turbines & structural components. Our portable hardness tester can test at any angle, even upside down. It is suitable for wide measuring range for all metallic materials. It can be connected to a PC via USB port & has software calibration function.
