Ultrasonic testing has been widely used in medical, metal and other industries. Among those industries, ultrasound testing on cultural heritage is relatively rare and unique due to the special features of the ancient stones, ceramics and other relics. The combination of pulse velocity measurement and waveform analysis helps to evaluate the inner/outer properties of cultural objects. In addition, the homogeneity and defects in the objects may be measured with the waveform display.
MUC® system is the latest and by far the most advanced ultrasound tester which is solely designed for the cultural heritage application.
Cultural Relics which could be tested:
• Sand stone
• Ancient stone

|Pulse Repetition Frequency||2Hz and single shot|
|Synch Signal Output||TTL|
|Transmission time||0.1-9999 μs|
|Pulese ON / OFF||externally controlled by TTL input|
|Power supply||230V / 50 Hz ; 110V / 60 Hz|
|Three different types of ultrasound emission:
• direct (both sides of sample)
• indirect (same side of sample)
For example, long-term stone stability through regular conservation and monitoring involves:
Step 1: preparation of a good reference stone sample which represents the original status of the objects (either by drilling a block from the object or by preparing it);
Step 2: the use of the automatic lab stand system with the ultrasound generation system to mea sure the reference stone samples;
Step 3: the use of the ultrasound generation system to measure object on site and compare with the reference data to evaluate whether there are potential cracks.
* Comparing with the manual pressing of the sensors by hand, the lab stand system is able to produce a standardized and more reproducible pressure on the sample.
* The velocity data and other parameters will be automatically shown on the electronic box or computer. These can be further used to determine whether there has been any change in the mechanical stability, or to evaluate the mechanical properties of those materials which will be further used for renovation and consolidation on the objects.
