Search Measuring Signaling device ISP-Pm1703Gna-II
Principle of operation
The device is equipped with two highly sensitive detectors: a Csl (TI) scintillation detector and a 6 Lif / ZnS neutron detector and is designed to detect and localize gamma and neutron radiation sources, as well as to measure the individual dose equivalent (DER) and individual dose equivalent (ED) )
When exceeding the established threshold levels (DER, gamma or neutron channels), the device gives light, sound and vibration warning signals. In search mode, the count rate for gamma and neutron channels is displayed on the device screen in pulses per second.
The non-volatile memory of the device stores up to 1000 events that can be transmitted for further processing to a PC via USB, or via Bluetooth (for modifications of the ISP-PM1703GA-II BT / PM1703GA-II MBT) to a smartphone / tablet.
The device is simple and convenient to operate, has a low weight and compact size. Shock-resistant and moisture-resistant housing allows the device to be used both indoors and outdoors.
Categorization of radionuclides
Upon reaching the threshold level on the gamma channel, the device categorizes the detected source. When the source belongs to natural (NORM) radionuclides, a flashing green light is emitted. If the detected radionuclide is of a different type, a flashing red light is emitted.
ISP-RM1703GNA-II - basic modification
ISP-RM1703GNA-II VT - differs from the basic modification by the presence of a Bluetooth channel
ISP-РМ1703ГНА-II МВТ - differs from ISP-РМ1703ГНА-II in the extended DER measurement range, the presence of the ED measurement mode and the Bluetooth radio channel
The device can be delivered in a special case, which provides additional protection in adverse weather conditions and accidental falls.
