RadonEye Pro Detection Kit


Radon is an odorless, invisible, radioactive gas naturally released from rocks, soil, and water. Radon is a chemical element with the symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas.  Radon can get into homes and buildings through small cracks or holes and build up in the air. Over time, breathing in high levels of radon can cause lung cancer.

A 20 Ah battery has a 72-hour life. A 30 Ah battery will increase the battery life to approximately 105 hours.

What does the RadonEye Pro package come with?

The unit ships with a tripod holder, step-up cable, adapter extension cable, battery pouch and carrying bag for inspection (except the tripod, battery itself), and calibration certificate.

I can't read the screen because the text and background color are the same. How can I fix it?

To change the display settings, go to Settings –> Display & Brightness –> Check Light Appearance (Not Dark mode)

Does the Pro generate a report in Becquerels?

Yes, units can be changed using a toggle within the set-up software. However, to generate a report with the changed unit, when setting up the device, you need to connect to Wi-Fi and save the changed unit to the server.

Can the device be attached to a tripod?

Yes. The unit comes with a tripod adapter (not a tripod itself).

Can I turn off the readings on the display?


What is the latest version of the RadonEye Pro software?

For iOS: iOS 2.0.0
For Android: Android 2.0.1

Does the Pro have any tamper monitoring?

Yes, an accelerometer. It shows the time the device was tempered in the raw data and app.

Does the RadonEye Pro have a reset function?

No, there is no function to reset the device.
It can store up to the following:
– Inspection mode: Max 240h x 10 (2,400 data points)
– Continuous mode: 300days (7,200 data points)
– When the data storage capacity exceeds the capacity, the oldest data is deleted.

How do I access the web dashboard?

Log in to the homepage.

Do I need to be connected to WiFi to use the RadonEye Pro?

No, the smartphone app connected to the device via Bluetooth is all that you need to set the length of the test, start it, download the test data, and generate a report. If you are connected to WiFi, you will be able to monitor a test while in progress, but not start or stop the test.
