The GQ GMC-320-Plus digital Geiger Counter is an enhanced version of GMC-320 and GMC-300. It added new features from previous model, such as front LED indicator, analog data port output, new graphic type etc.
It is designed 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 be used for 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-320 Plus internal rechargeable battery can be charged with the supplied wall adapter or with the car adapter for the cigarette lighter. 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-320 Plus Soft Geiger Counter software and the GQ Geiger Counter Data Viewer software. 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 and analysis. For professional data logging of radiation data, the GQ Geiger Counter Data Viewer(Logger) may be downloaded for free. An even more advanced version, may be purchased at low cost from GQ Electronics LLC.

P.s. The firmware upgrade has to be done in house which is extremely inconvenient. It might have been worth the bugs if they released a firmware upgrade that could be done by the user.
The unit worked just fine for what I wanted except for the data log. It was very random at times, it would sometimes keep a record for the entire day (1440 records), other times it only kept 200 records for the day. It also was limited/varied on how many days it would record until it dropped or missed days.
I also have a Mazur 9000 unit, very good, more money, but it will track a whole month of data and not miss anything. Its just a little more difficult to extract the data and the cost is higher.
The GMC unit is ok for very basic stuff I guess, but maybe my unit was a little flakey.
Update: As of 2/22/15, no problems with the GMC-320 unit and still sending data reliably to NETC.com through the Raspberry PI and my wireless router.
What's really neat is you can put this unit in a cell phone holder in a car while driving and observe background radiation as you travel. What would be really neat is if you could attach a usb gps sensor to it and gather coordinates and make a heat map of background radiation and overlay it on a map. Hrm. Maybe I can attach it to a cell phone and use the cell phone to do the dirty work of getting location data and logging it.....

Does it's job very well the only back fire from it is it doesn't give you a calibration sticker or letter saying what it's calibrated for i.e. Cesium 137 etc.Published 1 month ago by Amazon Customer

Got this about 4 months ago. I am measuring 24 cpm, normal for this area. I am using the counter with the PC software to monitor the environment locally. Read morePublished 11 months ago by TahoeJohn
Works well and was what I was expecting. However, could be easier to setup (as in a few how tos), on Linux, but a bit of googling and I found radmon.org which was very helpfu.Published 18 months ago by Ray Brannam
