PCUZ-1-1-BMD Gamma Radiation Level Detector

The meter measures the equivalent dose rate of gamma radiation 0.1 to 10000 R/h in the energy range from 80 keV to 2.6 MeV with the output of information in digital form to the medium frequency control unit (BIO-05).

Ecofizika-500 is a multifunctional modern platform for building complex measuring systems. The developed software makes it possible to fully use the powerful hardware potential of the system in tasks requiring the use of complex computational algorithms. Ecofizika-500 is not just another multi-channel frontend designed to transfer unprocessed data to a computer; it is an independent measuring device capable of calculating a huge number of quantities in real time, storing them in its own memory and (or) issuing them to a telemetry channel. The device can be used, including in offline mode, as a data logger, which is very important when testing complex equipment that limits the presence of the operator. Ecofizika-500 has an approved type of measuring instrument and methodological support for measuring acoustic and vibrational quantities.
