5 from 5 RadonEye

wow, nice product. The radoneye is much better than the corentium home / canary device, because you can see the current radon value directly on the display. this is perfect for us, because if the radon level is to high, i can open a window.. good device, thanks for support

5 from 5 used in different buildings and rooms

we find radon in some old houses, old restaurants or a meeting room, in a cellar from 400Bq until 1200.
In our apartment we have from minimum 14Bq until 45Bq
In our new office building we have two parts one classical from beton& bricks 60-90 Bq without ventilation and 30-65 Bq in the metal part of the building. With ventilation system with heat exchange, the values are significantly reduced.
Also significantly increase the value, if Radon eye are placed near floor traps or in the bathroom.

5 from 5 Easy to use and fast

Easy enough to use - just plug it in! Seems to find accurate measurements very fast. Havent tried it with the app yet.
Shipping was very fast!
I will not hesitate to order things from RadonShop again!


The product came ina good package in three days from Germany to italy.
This is my second RadonEye. First thing done was compare two devices with a Canary (a good domestic device)
All three device after 5 hours had similar result with a difference: two radonEye was much faster and had a log to compare :)
Simple to use, plug cable and wait 10 minute, then look at value measured. It signs actual , peak, 1 day mean, 1 year mean, counter of calculation.
You can also use app to see log and set alarm (a beeper that advices you when a unwanted value of Radon is reached.
Until now im very satisfied by product.

Question on item


Yes, the RadonEye can also be operated with batteries. This requires an extra 12V/USB cable. With this cable the RadonEye can be connected to a normal (mobile) PowerBank. Depending on the size of the PowerBank, the RadonEye can be operated mobile for up to 2 or 3 days. 

Test report RadonEye

Product recession RadonEye

We at Radonshop. com have tested the new radon measuring device RadonEye for you. This device is the latest development from FTLAB - a well-known manufacturer of innovative and high-quality radiation measuring devices. In our test we will show you the advantages and disadvantages of this device and tell you for whom this product is particularly suitable.

Unboxing and first impressions

The RadonEye is delivered in a white cardboard box in which the radon measuring device is safely stored. Special holders inside the carton ensure that the measuring device arrives safely at the customer's address, even when it is sent by post. Inside the box is the radon monitor, its power supply, a 12-volt USB cable, a small manual and a quick reference guide. There is also a certificate about the successful calibration of the measuring device. The fact is that every RadonEye meter has been tested by the manufacturer and calibrated according to international standards before it is sold. We already find this circumstance great, because we can start with the measurements right away - and with great certainty we will get very precise measurement values.

After unpacking, we turn to the RadonEye itself. What can the device do and how well is it processed? On the first impression we like the RadonEye very much. It is about 12 cm high and has a diameter of 7.5 cm. The design is visually reminiscent of an I-Phone. With a weight of 300 grams, the RadonEye has the ideal weight; not too heavy to transport and yet heavy enough to stand securely. Rubber feet on the underside of the device further increase the stability. A small colour display on the top side shows a clearly legible blue and orange-coloured text after connecting the power supply unit. The readability of the measured values on the display is excellent in both darkness and light.

First commissioning

power supply

As already described, the RadonEye is operated with a 12-volt power supply unit, which means that the device cannot be carried around as you please. Due to the power supply, the RadonEye relies on a wall socket and is therefore only suitable for measurements in rooms with a corresponding power supply. However, we did not want to accept this: That's why when you buy the RadonEye, we'll include a 12-volt USB cable with which you can connect an external battery/power bank at any time. The cable is able to raise the voltage of a 5-volt power bank to 12 volts, so that the RadonEye can be easily operated with such a power bank. This measure increases the mobility of the measuring device enormously, so that radon measurements are now also possible outdoors or in remote locations. External rechargeable batteries can be found almost everywhere cheap in electronics shops. You can buy a Powerbank there for only a few euros.

Start procedure and display

So, now we have connected the power supply and see that the RadonEye starts up. This process takes about 20-30 seconds. Then the colour display lights up and the RadonEye starts with the first measurements. The display is preset to Bq/m3, but can also be set to pCi/l. The lower part of the display also shows other values alternately, which would be important for a longer measurement. This includes, for example, the measured peak value, the total duration of the current measurement series and a long-term average value. A particularly positive feature is that all important values are displayed automatically. Therefore there are no further control buttons on the RadonEye. The device is therefore very easy to operate and there are no components attached to the housing which could wear out or break over time. But even without operating buttons, you can display the measured values exactly and with time resolution - with the corresponding smartphone app.

smartphone app

The smartphone app "RadonEye" belongs to this device and can be downloaded free of charge for Android and iOS. To get to the app, we just had to sign up at the playstore or appstore. Under the term "RadonEye" it could be found quickly. The software is installed after about 3-4 seconds. Since the app is only 2 MB in size, it ran smoothly on all our devices (smartphone and tablet). If you do not have a smartphone or tablet, you can easily read the measured values from the RadonEye display. However, the app improves the display and some data is available to help you find out more.
