Description

Overview

U9XX series crosshole sonic analyzers are top-of-the-line instruments designed for
comprehensive non-destructive testing (NDT) of non-metallic materials, including
concrete and rock mass. The series is developed by IWINTESTING EQUIPMENT
and supplied by Kreator Lab BG as an official representative.

The devices are extremely easy to understand and operate, yet they provide top-quality data
on integrity, strength and other valuable mechanical properties of non-metallic materials. They are ideal
for defect detection and defect shape measurements in a wide range of
civil engineering and geotechnical applications.

U9XX series analyzers are perfectly suited for:

• pile integrity testing
• structural concrete compressive strength assessment
• diaphragm wall integrity testing
• geological exploration (e.g. rock integrity and weathering evaluation)

The U9XX series utilizes ultrasonic wave propagation to collect the most useful information
about the object under investigation, making it a powerful tool for non-destructive evaluation of
concrete structures and rock formations.

Measurement principle

The U9XX analyzers are based on the ultrasonic wave spreading properties in non-metallic
materials. By transmitting and receiving ultrasonic pulses through the material, the system measures:

• acoustic travel time and its accuracy,
• amplitude and waveform of received signals,
• changes in signal characteristics caused by defects, cracks, inclusions and other discontinuities.

These measurements allow the user to assess material integrity, detect defects and evaluate strength-related
properties without damaging the structure.

Key features & benefits

  Built-in electronic hard disk (> 8 GB) plus support for large-capacity U disk for extended data storage.
• Efficient data acquisition
  Double receiving, automatic collection and automatic recording of height and sound waveform to significantly
  improve work efficiency.
• Waveform playback & editing
  Original measuring point waveforms can be played back, overwritten and deleted, allowing detailed review
  and data management.
• Ultrasonic rebound method compatibility
  Can be connected with a digital rebound hammer probe to implement an ultrasonic rebound comprehensive method.
• Powerful PC software
  Supplied with powerful analytical software for PC for advanced data processing, reporting and long-term storage.

Typical applications
