SAF Aranet Radiation Detector, Dosimeter, Portable, Measures Dose Rate & Total Dose of Ionizing Radiation, E-Ink Display, 4-Year Battery Life, Bluetooth Connection, Free App with Graphics & Alarm

These units are well packaged, easy to hook up to Bluetooth and have a great display that can be seen easily from many angles. Get ready for a lot of available information.

As a geek, I have many Geiger counters from professional to small pocket size. The only problem is they stay turned off. If you leave batteries, the batteries can leak and do a lot of damage, corrosion I the battery compartment. So I store with out batteries. This unit is accurate. I have it wall mounted. I can pick up my iPhone any time to get a reading. It graphs out everything and stores on phone. There will be an alert if the nuclear power plant south of my city leaks or WW3 starts. I am not in fear, just a geek. Back to H.P. Lovecraft now.

Aranet delivers an excellent product that provides accurate data. I use this Ensor in my house and have been very satisfied with its performance.

Good unit for home monitoring. Batteries last for months. Use Case is nuclear accident scenario and knowing where not to be. Ordered another unit for vehicle.

These meters are insanely useful for your radon situation and CO2. Lots of dynamic readout, just hop on your phone and enable bluetooth.

The only reason I give this 4 stars instead of 5 is because it's lacking the spec sheet. They provide a link to their site, which is broken. When I search their site, I cannot find the information. This is accurate for detecting radon - it's coming up with the same rating as my other radon detector (low levels in the basement). But I'm curious how sensitive it is, and if it picks up higher frequency non-ionizing radiation - and I cannot find the answer to this. But this is really a smart easy device. Just unbox, pop in the 2 AA batteries (included), and it's up and running in under a minute. It does have an optional app component. The app will tell you the history of the readings - if you're having spikes, for example. It connects with your phone via bluetooth, so it's not remote monitoring or anything like that. It only provides history, and you must be close to the device (within bluetooth range) to download or update the history. Someone else said the app was necessary to set up the device, and I don't know what they are referring to. I suspect they got confused since it doesn't come with an instruction booklet - you have to zap the QR code or type in the URL to read the directions. But that is different than the app. I have seen other radon detectors in this price range, but none of them have this history function. You may not need the history - my levels seem pretty steady, and the device gives you a running average which is generally the most important thing to have. But the precise history is a nice feature and surprising to find on a device this inexpensive.

The product matches the description, And works out of the box without any needed configuration, the connexion with the application is straightforward

We have gained a lot of insight into our indoor environment's air quality thanks to our SAF Aranet4 unit, so when I saw SAF had created an Aranet Radiation Detector model in the same familiar (and compact) footprint we were further intrigued about what it could tell us about the background radiation in our area, the background radiation in areas we travelled in, and even the background radiation in our home where there's the possibility that it could be present in small amounts due to the local geology. When this unit arrived, I installed the included batteries according to the label (pay attention to the alignment as both go in the same direction!), and the unit went to work taking readings and doing its internal setup and stabilization steps. Once all of the self-setup was complete the display indication changed accordingly, and normal operation continued uninterrupted. The app was easy to use, since I already had experience with it from my Aranet4 device, and adding this unit to my profile in the app was very easy. Of note, the buzzer/beeper described in the manual for the unit and the beeper described in the app settings are two different functions and are not interconnected. Out of the box, the default setting for the Radiation Detector is for it to make a little chirp when its detected level changes. Some folks might want this, or be able to ignore it, but for me it got to be a little much. Once I realized the app setting had no control over the device beep, I re-read the instructions to review the description of which of the DIP switches set which option. Once I knew which one I need to flip, I turned the unit over, opened the battery compartment, removed the top battery, and used the tip of a sewing needle to flip the little switch to the non-beeping side. I then replaced the battery and put the battery compartment cover back on, and the unit didn't miss a beat. And, most importantly, the little beeps stopped. If I take it out on a hike or somewhere that I'd want to have the higher level of awareness, it will be easy enough to flip that switch back to the beeping side. I appreciate how easy Aranet made it to control that behavior! Of note though, do NOT make any of those changes once the initial startup procedure has begun as you have to remove a battery to get to the switches and that would interrupt the process. Wait until the front display indicator turns off and you can see that the unit is in normal operation only. After a couple weeks of operation, I now have a good history of background radiation in my home, and I can see the trend of high and low levels daily. It will be interesting to see if there are any different trends seasonally or if what I'm seeing so far is a true baseline. Information like this helps me understand and respond to my environment so that I can take actions in pursuit of better health for myself and everyone in my home. This Aranet radiation detector from SAF represents a big leap in terms of reliability and miniaturization for such detectors and makes portability far easier than previous generations of handhelds. I love it!

Tolles Gerät! Sehr gut ablesbares Display und top Datenlogger-Funktion mit der App. Gerade diese macht es so interessant wenn man den zeitlichen Verlauf anschauen will oder Daten exportiert. Batterie hält auch lange.

I already had the Aranet 4, so this was the obvious choice. The e-ink display is much better than other devices on the market as it means the battery lasts much longer. Only downside to this is it cannot be wall mounted like the Aranet 4 can be.

Excellente ergonomie. Mais comment tester son bon fonctionnement ? Bien entendu j'étais conscient de cette difficulté lors de l'achat. Aucun regret malgré tout.

Very cool technology was a very nice package and a smart function integrated battery are still almost full after more than 100 day of operation
