EUT-302 Digital Ultrasonic Detector

EUT-302 is a kind of pocket detectors specially produced for ultrasound flaw detecting with great mobility, like high overhead work of steel structure Though it’s small in size, it is portable and with high performance EUT-302 is designed with A B scan display on the screen at the same time The thickness measurement is in high precision The dynamic echo record can be replayed for up to one hour Various thickness measure methods are designed for different thickness Besides the measure of sample thinner than 0 5mm and corrosion pit in tube ID with coating, this instrument can monitor the thickness measure result with A echo, and store and imaging with B scan So, this instrument can be used for UT imaging of high-voltage porcelain insulator, welding inspection, UT flaw detection and thickness measure of auto parts etc
