Overview

Measurement performance: The dose rate measurement range is extremely wide, from a lower limit of 10nSv/h to an upper limit of 10Sv/h, which can adapt to the monitoring needs of various radiation intensity environments. The energy measurement range is 50keV -6.0MeV, which can effectively detect common gamma ray energies. The detector adopts an Ar filled spherical high-pressure ionization chamber (≥ 2.5MPa) and a combined Geiger counter
