GQ GMC300Eplus Fulfill Digital Geiger Counter NULCEAR Radiation Detector Monitor Meter Dosimeter Beta Gamma X-ray Datalogger Recorder Real-time monitoring, private home use All purpose, wall charger

Face item appears to be well-made and accurate, it is within 00.01 to 00.02 of my secondary reader, and less a good time on a charge.Small enough to be discreetly placed in their home, measuring background radiation, ideal if you live near a nuclear plant or an industry that uses nuclear products in manufacture. To give you that extra little time right up in saving yours and your family’s lives.Easy to use, easy to set up, would recommend this product in your prep kit or for just piece of mind or curiosity of background radiation where you live.

Long battery life and measured background radiation matches expectation for my geographic area. The data storage capability is quite useful as well. I have not tested this device using calibrated beta, gamma and X-ray sources, but I suspect that the performance would be pretty good. Note that these types of detectors generally do not measure alpha or neutron radiation. I purchased this device for testing for residual radiation in building materials and antique plate glaze and I am very satisfied.

works as expected. you don't get A measurement at this price range of course, but this is not much different to the GMC500 plus really, it reads and graphs pretty much the same without useless features like wifi etc.

There is different types of radiation but I tested this out on a long haul flight.As soon as we hit 5000 feet the count starts to increase and is higher again at 30000 feet.So as far as cosmic radiation gos it detects it. I will take it for further testing but so far so good.

I dislike there is no app for the phone it have no BluetoothNo waterproof instructions a joke , NO ESTANDARD USB PORT. I LIKE a lot features in one device , battery life is very good even in negative degrees -5⁰Tested, tube inside can be change but you have to know what are you doing , can be set in the wall it come measure guideFor 79£ I can't ask for more Other device will charge you twiceI forgot my favourite feature is power saving but if you put headphones you can hear they device working clicksIs comesRecomend yo buy more advance device to keep standby when this one detect too much radiation .Life expectancy for this devices is 2+ years in heavy use but as I said you can change de tube sensor soo this device can be use for much longer also put ptlrotection to waterproof it but only will measure gamma like that actually measures better and gamma no alpha but I'm not 100% sure they don't provide this info.

Got this at the right price to check whether any of the watches I’ll be working on have radium in the lume.The model has been updated since some of the reviews I read, it now has a USB-C socket for charging and connectivity.I did a quick check when I received the Geiger counter by waving it over a few watches and, sure enough, it could tell the difference between modern lume and that nasty radium stuff.It is quite configurable and just so you know - the GM tube is at the top of the unit, above the display, not to the right where the nuclear emblem is…

I cannot comment on the accuracy of the device nor its reliability in situations where one's life could be at stake...(I am sure there are some properly certified and 00's times more expensive devices for these purposes).I bought it specifically to make my daugther's GCSE preparations more interesting, by being able to 'demonstrate' the mysterious radiation - and can confirm it works nicely with the source available to me (which is a victorian 'uranium glass' bowl).I also like the fact that, in addition to modern data representation and logging (numbers, graphs) it also simulates good old 'clicks' from early Geiger counters - a chilling sound, reminding me of some doomsday films...

The build quality is good and it works really well

I wanted this mainly to determine if I or family have rocks/pottery/glass that might be a gamma/Beta radiation source. So, this fit the bill as it was quite inexpensive and had the accuracy that I needed.To test, I would place the unit where the sensor is located (bottom of the unit) on top of an ionization based smoke detector. The CPM would rise to about 55 CPM versus a background radiation count of 10 CPM.Good to have around to determine if there is any ionizing radiation is being emitted by objects around your home.

Parfait et facile d'utilisation.

Great Machine it works acurate

Mein Katze bekam eine Radio-Jod-Behandlung, und ich konnte die Werte der Klinik mit dem Gerät gut nachvollziehen. Mit dem Zähler kann ich zu Hause checken, wie viel Reststrahlung in welchem Abstand in Katze und Hinterlassenschaften noch vorhanden ist. Der Zerfall von Jod 131 erzeugt Beta- und Gammastrahlung, die das Gerät erfasst, in guter Übereinstimmung mit den Messungen der Klinik.Man kann durch eine Reihe von nützliche Display-Optionen durchklicken und eine Menge Optionen einstellen wie z.B. Schwellwerte für Alarme.Das Gerät wird per USB Mini (nicht Micro)-Buchse geladen. Der Akku hält, selbst mit Display-Beleuchtung, leicht mehr als einen Tag Dauerbetrieb.Über USB gibt es auch eine serielle Schnittstelle (Protokoll ist offengelegt), mit der z.B. das gute Python-Programm (dadurch ist das Betriebssystem egal) "geigerlog" zusammenarbeitet. Ich lese damit den Speicher aus und logge live mit. Man ḱann damit auch Datum und Zeit setzen. Wie andere schon schrieben driftet das Gerät pro Tag schon mal 15-30sec.Alpha-Strahlung wird, wie beworben, NICHT erfasst, so dass meine Uranglas-Dose keine Reaktion erzeugt - dafür sind (teurere) Sensoren mit Alpha-Fenster erforderlich. Wenn ich Rezensionen lesen, dass das Gerät in Tschernobyl/ Pripjat gute Dienste geleistet hat, dann hoffe ich, dass den Rezensenten klar war, dass sie dafür das falsche Gerät dabei hatten, weil es die dort relevante gefährlichste Strahlung gar nicht registriert.

Prodotto base per uso casalingo ma fa bene il suo lavoro. I dati sembrano abbastanza affidabili, ha diverse possibilità di personalizzazione dei dati e la batteria ricaricabile dura molto (se usi lo stand by) ed è facilmente accessibile nel caso si debba cambiare.NON rileva le radiazioni alfa e purtroppo il software disponibile (logger e viewer). Per il software vi conviene usare u open surce python fatto molto bene che trovate su github
