Sistema para Monitoreo de Áreas con Visualizador de Datos AT2327

AT2327Alarm dosimeter is intended for radiation monitoring of radiation-sensitive and radiation-dangerous areas and facilities.








Operating principle

Gamma smart probe is used for measuring of radiation background level.
Dosimeter operation algorithm provides measurement continuity, rapid reaction to background radiation level change and real time display of detection unit data on external display.
Ambient temperature and current time and date is additionally displayed.
Control unit is responsible for controlling the operation modes, performing necessary calculations, storing and backing-up measurement results, as well as for supplying power to devices. It hosts command console, interface adapter and backup power supply.
Control unit is to be installed indoors.
