Our enterprise has been operating in the field of development of instrumentation and testing equipment for space industry for over 50 years. Basing on the experience of designing electronic products we have developed a multiplex strain measuring system, which is currently in operation on the strength test stand of aviation structures at ANTK «Antonov».

Automated information strain measurement system (/ATIS)
