GQ GMC-300E Plus is a newer model of GMC-300 series Geiger Counter. Compared to the previous model, GMC-300E Plus improved overall quality. It installed a high contrast black/white LCD module, added a front LED indicator/an audio data port. The audio data port can be directly connected to any third party device application as data input, such as iPad.
It is designed to be a portable/convenient device. It has built in audible and visual signals for the level of radiation detected. It can be used for nuclear radiation detection and monitoring both indoor and outdoor, as well as in other similar environments. It features automatic data recording. It can continually monitor the radiation and log the data each second into internal memory. When connected to a PC, software can download the radiation history data to the computer and the user is able to analyze those data later.
The device is equipped with an USB port, utilized for communication and external power supply/charging of the internal rechargeable battery. The GQ GMC-300E Plus internal rechargeable battery can be charged via a wall adapter or via a car charger through the car cigarette lighter. By using the adapters, continuous data monitoring is possible. Using either power adapter you will not have to worry about the batteries charge condition or any data loss.
The main board also has a real time clock on board for time related data logging purposes.
The USB port communicates with the GQ GMC-300 Soft Geiger Counter software and the GQ Geiger Counter Data Viewer software.
The GQ GMC-300 Soft Geiger Counter software’s appearance is an exact copy of the GMC-300 hardware human interface. You can download it for free and explore the GMC-300 user interface before you purchase the real hardware.
The GQ Geiger Counter Data Viewer software can download the time stamped radiation (history) data from the unit and save it on a computer for future references analysis.

The units can be changed from μSv/hr, CPM, or mR/h.
Detector tube can be replaced when it's useful life has ended which is nice. I've read that the tubes can last 6-8 years, some people reporting longer. It can be re-calibrated if necessary.
I would have given it 5 stars until I installed the application.
First impressions of the GQ GMC Data Viewer application on Windows 7... Looks like a dated and hastily thrown together MFC application with few features and low aesthetics. On the plus side... Installation was easy. My PC connected to the GMC-300 painlessly and without problems. The application collects data stored on the GMC-300 and also has a real-time display feature. The graph is scalable and even has auto scaling. You can save the data as a .csv for excel or graphing use. That's about all it does. However, If you have knowledge of programming, this is an "open protocol" device and they do provide information on incorporating the GMC-300 USB-serial connection into your code projects.
Drawbacks to the application... I have to set up the COMM port for its USB to serial interface every time I launch the program even though Windows Device Manager is able to detect and display the correct COMM. I'd be very surprised if the USB to serial API for Windows doesn't have a way to detect COMM port. Even if the API didn't have an easier way, they could still check each Comm port until the unit responds through one of them. Disappointing. Even though the GMC-300 unit itself has an alarm for high level radiological events, the software does not. The application seems to be pretty dumb... take the data from the GMC-300 and put it over there in that file and then do nothing more with it.
I installed the demo version of the GQ Geiger Counter Data Logger pro-application which they want an additional $9.99 USD to activate. It is supposed to be a more feature rich version of the GQ GMC Data Viewer application. Honestly... why companies still do the "9.99" thing, I'll never know. It's 10 dollars, just say 10 dollars... seriously are we all four years old? Ok, so I could get a one penny discount for their $10 program; what do I get for that?
Still looks like the same dated UI as the application that comes with the GMC-300. There are a few more options on how to display units over time. The graph displayed in real-time mode seems like it might be a little more useful, showing an average over time instead of just counted hits over time which is an improvement over the included app. I don't know what the averaging window is; it doesn't say. I would assume over several seconds because it seems to go up and down with a curve that is pretty close to the second per second hit count. I still have to set my COMM port each time I launch. It does give a few more ways of viewing data. It has some options that are grey'ed out I assume because I'm running the demo version. There is an OCOC Wizzard that is grey'ed out; don't know what that does. Also, a grey'ed FTP menu; that sounds intriguing... and a grey'ed out "other" menu. Is that how you get to the others on Lost? I know... bad joke.
In conclusion, I really wanted to give the GMC-300 five stars. The device itself deserves five stars but since I'm rating the whole product which includes the ability to interface with your computer and the software included which is important, I can not. I would like to see a little more effort on the application side of things. Please, GQ Electronics, improve the whole package which includes the PC interface. Please make this the product I know it can be.
Still, overall a great product but I need a better way to use the data without writing my own program which I don't have the time to do. I would pay for a fully featured app but your 9.99 app doesn't have enough obvious features.
Update: Mac support would be nice too. I have several friends who use Macs who would be interested in this. Porting software to Mac could be done without too much trouble and could gain many more customers.
Really the only criticism I have of this unit is that it has mini-USB, not micro-USB. Mini-USB has been obsolete for years, so don't lose the cable that comes with the unit because you probably don't have another one lying around your house.
