Product Description

A compact handheld ultrasonic pulse velocity and pulse echo tester is designed for ultrasonic thickness measurements and flaw detection of concrete and reinforced concrete constructions and rocks.

The flaw detector represents an compact electronic unit is equipped with a large high-contrast TFT display and a keyboard.

Despite multifunctionality the instrument is easy to use due to its intuitive interface and icons menu providing quick access to main settings and functions of the instrument.

Ergonomic design of the flaw detector and its light weight (as little as 800 grams), as well as capability of fastening the electronic unit in the specialized pad, provide convenient operation of the instrument in hard-to-reach areas and allow its working at height.

All inspection results are recorded into the instrument’s memory and can be transferred via the USB-port to the external PC for further processing, registration and archivation.

Application

The «CLASSIC» version of the device with 2D projection imaging function is included one of 24-element matrix antenna array М2502 0.05A0R100X60PS is connected to the electronic unit by the LEMO-LEMO double cable. This antenna array operates like a double-crystal transducer. Its elements are spring-loaded thus allowing operation on rough and uneven surfaces.

Using one low frequency dry point contact antenna array M2502 0.05A0R100Х60PS with shear wave and nominal frequency 50 kHz allows carrying out thickness measurement of the concrete objects up to 3 000 mm and reinforced concrete objects up to 600 mm.

The instrument allows to operator search for internal foreign inclusions, cavities, voids and cracks of the products and constructions made of reinforced concrete, stone and similar materials at one-sided access as well as search for embedded flaws of bronze castings.

It is possible to testing of the internal structure of the coarse-grained materials.

The results of inspection are slice and projection images by grid-scan function (B-Scan, C-Scan, D-Scan, thickness-profile) – visualization software INTROVIEW.
