This item is a brand new GQ GMC-200 Geiger Muller Counter Nuclear Radiation Detector with Data Log Software
The GQ Geiger Muller Counter is designed by GQ Electronics LLC, USA. It is to be a portable and convenient device. The device comes with built-in audible and visual signals for the level of radiation detected. It can used for radiation detection, monitoring in house, out house and other similar environment. When it connected with a PC software, the radiation level can be continually monitored, recorded and analysed , 24 hours a day.
The device also comes with a data output port, so that to communicate with external PC Windows software: the GQ Geiger Muller Counter Data Logger. The software is able to log the radiation data in real time. User is able to analyse those data in different ways. The data can be saved as history data.
The GQ GMC-200 installed a high capacity rechargeable battery. With power adapter, the battery can be charged while the data continually monitored. So never worry about the battery and lost data.

This video testing used three radioactives during the testing. The first testing uses vaseline uranium glass beads (d=5 mm) of quantity 24. The second testing used a Uranium Ore. The third testing used a standard 5uCi radioactive. The GQ MGC-200 Geiger Counter connected to a laptop as well as a power adapter for charging battery. The Windows Software shows the radiation activities.
The LED flashes when the radiation pulse is detected. A "Click" sound can be heard at same time.
Higher frequency "Clicks", the higher radiation detected.
Data port for communicating with PC software.
