The velocity of ultrasonic wave in concrete is affected by elastic property or strength.

Ultracon-170 applies high voltage and sends it to transit transducer to generate ultrasonic wave. This ultrasonic wave reaches to the receive transducer through concrete. When elastic property or strength of concrete is high, the transit time is short. On the other hand, when the materials are contrary, the velocity is low.

Ultracon-170 measures the ultrasonic transit time accurately so it makes possible to evaluate a material or find elastic properties non-destructively to investigate uniformity, cavities, cracks, fire/frost damage, delamination, deterioration and strength.

Ultracon-170 uses 54 kHz concrete transducers manufactured by mkcndt which were designed to send and receive ultrasonic signal effectively in highly attenuative materials, including concrete, wood, stone and plastic. This instrument was developed by cooperative research with Korea Research Institute of Standard & Science, subsidized from the national coffers of Ministry of Science & Technology. This is the 4th generation.

Features of Ultracon-170
With excellent analog circuitry design, the repeatability and accuracy is superb.
The color of LCD background is changing according to measurement mode.
Direct read-out of transit time of ultrasonic in concrete with ultrasonic transducers, which is pulsed by high voltage
With the combinations of high-energy pulser, high sensitivity receiver and high efficiency transducers, it is excellent in thick and attenuative materials.
TFT color LCD makes it easy to operate in work-site or laboratory.
Status messages and different color display according to measurement modes enables to ascertain present inspection modes.
12 x AA rechargeable batteries enables 5 hours operation with 1 hour charging.
Displays the transit time in 0.1μs unit
RF waveform can be observed through RF output connector to oscilloscope or optional A/D board
It is possible to connect 2 through 16 transducers to observe the change of ultrasonic transit time according to time lapse using mortar container, multiplexer and PC (option)
Rugged Aluminium case
Low Battery status display
