(I can recommend AE analyzers from Czech company Dakel.cz that we use in our lab during nano/micro – tribological/mechanical experiments. We need to sense very low-energy signals so we were looking for analyzers featuring the lowest-possible noise. Dakel.cz also manufactures AE sensors and they have designed a few optimally shaped and tuned for our needs. High flexibility in both hardware design and various software optimizations is a great differentiator of that small Czech company comparing to other vendors. Their support of our efforts was outstanding.
I know Dakel provides AE equipment for classic NDT AE methods including large-scale installations in nuclear power plants. They also do training and certifications of personnel in AE diagnostics.)
