Product Description

A compact handheld ultrasonic pulse velocity and pulse echo tester is designed for concrete quality accessment, 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 easу 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 «STANDART» version of the device is included two transducers S0205 0.025A0R20Х20CL and firmware with A-Scan visualization imaging function.

Two low frequency direct liquid contact transducers S0205 0.025A0R20Х20CL with longitudinal wave and nominal frequency 25 kHz are used for trough transmission inspection concrete objects.

Using one transducer S0205 0.025A0R20Х20CL allows testing of anchor bolts from 20 to 40 mm in diameter of understructure of steel supports of the overhead control system. The anchor bolts of understructures can be inspected without excavation when access is granted to the upper end surface of the bolts with overall length up to 3000 mm.

When dealing with the stack anchor bolts the instrument can inspect the upper section of the anchor bolt up to its welding point with the reinforcement bar.

Besides the anchor bolts the instrument can inspect the extended objects (pipes, rods, reinforcement bars, sheets, etc.) by wave guide technique. Inspection is carried out on the end surface of the object.

Optionally, the device can be used with dry point contact transducers for surface and through transmission scanning for time-of-flight /sound velocity measurement.
