AT2327-2

Alarm dosimeter AT2327

Ons AT2327 alarm dosimeter systeem is ontwikkeld voor ruimtebewaking en gebied bewaking waar radioactiviteit voor kan komen.  Het systeem is opgebouwd uit detectoren die op strategische plekken worden geplaatst. Deze detectoren zitten aangesloten op een controller unit en op eventuele alarm units.  Het gehele systeem kan aangesloten worden op een PC en netwerk waardoor controle op afstand mogelijk is.
