Detector cu ultrasunete pentru defecte - NOVOTEST UD2301-MINI
Ultrasonic flaw detector UD2301-mini is designed for nondestructive testing of metals, plastics, glass, composite materials, weld inspection and thickness measurement of the various products and structures.
The Flaw detector allows user to detect various defects such as discontinuities, cracks and heterogeneity of materials in semi-finished products and welded joints, to measure the depth and coordinates of defects, the thickness of products, the speed of propagation and attenuation of ultrasonic vibrations (UT) in the material.
Ultrasonic Flaw detector is produced in small housing of optimal size for performing testing in tight spaces. The device has colour display with high resolution (320*480 pixels), which significantly improves it’s usability.
he picture on the display of the device can be rotated in 4 position, that allows to operate the device in any position, making it customisable for both: lefties and righties users, as well as positioning the Instrument in portrait and landscape orientations.
The use of the ultrasonic flaw detector:
- to test the quality of welds and base metal of products;
- to detect corrosion, cracks, delaminations and other internal defects;
- to determine coordinates and parameter estimation of defects such as discontinuity, cracks and uniformity of material in products from metal, plastic, composites and other materials;
- to measure the thickness of products.
The Flaw detector is equipped with 3 standard type AA rechargeable batteries. The device can also operate with non-rechargeable batteries of the same type. Using the batteries of standard type allows autonomous operation of the device in almost any conditions – if there is no possibility to charge batteries, it is possible to have spare batteries, or buy new batteries at any store. The Flaw detector allows user to solve a wide range of tasks – from thickness measurement of thin products to large-sized casting flaw detection.
Having sealed housing with rubber protective strips makes Ultrasonic flaw detector UD2301-mini ideal for using in workshop and field conditions with high humidity, dust, etc. The device has frost-resistant display that allows to use the device at any season and in any climatic zone of the Earth.
