New PRD «CADMIUM» Search Alarm Dosimeter DKS-02PN
Features
- New generation high sensitivity CsI scintillation detectors of gamma and LiI of neutron radiation with solid state (silicon) photomultiplier.
- Color display with high resolution.
- Integrated GPS/GLONASS-receiver.
- No “microphone effect”.
- High thermal stability.
- Audio and vibration alarm of threshold levels exceeding.
- Light color alarm (indication) of threshold levels exceeding (gamma radiation – red color, neutron – blue) and visual alarm on the side of the device.
- The dosimeter communicates with a PC via USB-port.
- Powered by built-in lithium polymer storage battery that can be charged via USB-cable.
- Ingress protection rating IP67.
