Gamma PRDs
Personal radiation detector PM1401MA is designed for detecting of gamma radiation sources. Due to its hermetic and shockproof case and the LCD screen fluorescent backlight, instrument can be used in extreme and harsh environments. For work in difficult-to-access areas telescopic extension tube is provided. PRD has audible, visual and vibrating alarms, records and stores up to 1000 events in non-volatile memory and transmits data to a PC via USB interface.
PM1401MA is recommended for first responders, security guards, police, customs officers and border patrol. No special experience or training is necessary to operate the instrument.
