Portal Radiation Monitor

EI-G3930 Portal Radiation Monitor

Product Introduction

EI-G3930 is a portal radiation monitor used for detection of luggages and pedestrians. It is equipped with two plastic scintillators which greatly improve the sensitivity. All of the advantages such as fast response, user-friendly software and automatic data saving allow the G3930 to be one of the most convenient portal radiation monitors for luggages and pedestrians at borders, customs, airports, nuclear plants, etc.
