2. GQ GMC-800 Multifunctional & Usage Description

Geiger Counter Dosimeter Radiation Monitoting Real Time Time-frame

GQ GMC-800 is multi-functional can be used as traditional Geiger Counter with clicks, real time & certain time frame measurement, dosimeter accumulation radiation on user body, continues radiation monitoring for certain location with certain time-frame.

As a traditional Gieger Counter: find the instantaneous radiation flux on a location/spot. Traditional find radiation source application
As a dosimeter multiple dose units: detect the real-time & accumulated radiation on human. Reading in different units shows at the same screen
As a Real-time & time-frame measure: display real-time radiation and time-frame radiation data and record and save data.
As a Radiation monitor (Graphic): continuous monitoring a location radiation over time. The unit can be connected with computer to monitor.

3. Ergonomic Design & Two Ways Power Supply


Mechanical Design Light (60g) Thin (1cm thickness) make it portable, easy to carry Premium material is used to realizes Anti-drop & robust	Where to Put the Detector Handheld Put in the pocket Stand up on both edges (short & long edge) Lay on the surface	Power supply Charge & Data transmission There are two ways to supply power. In-unit battery or power via USB port The charging cable is Type C Type C USB cable also facilitate data transfer	Battery Charge & Replaceable Lithium Ion rechargeable battery The battery can be take out any time for external charger. The battery is also replaceable when goes bad Battery can be charged in meter or take out charge via external charger The device detects battery orientation and halts charging if positioned incorrectly to protect itself.
