Accur-5 UT Thickness Gauge


ACCUR-5 ultrasonic thickness gauge made by our factory with OLED true color, built-in A-SCAN snapshot, great capacity data storage and through coating thickness function is a kind of high precision, new-type, and portable industrial nondestructive testing instruments according to ultrasonic measuring principle.


As the essential NDT instrument, ACCUR-5 can be widely applied in the detecting fields like manufacturing, metal processing, chemical industry, commodity inspection industry and so on. It can not only measures various kinds of panels and processing components precisely, but also monitor the thickness minus of tubes and pressure vessels in the manufacturing instruments after corrosion. 


All models of this ACCUR-5's gauges are standard with A-scan snapshot; it can help users better control measurement and avoid the inaccurate measurement value caused by the factor of material itself. And ACCUR-5 with great capacity data storage function can save a total of 100,000 sets of data, and can be output to the personal computer via USB to archive and data analysis. ACCUR-5 has through coating function: when there is coating layer on the surface of the object, the net thickness of the material can be directly measured without removal of the coating layer.
