A1220 MONOLITH 3D

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.
