RadonEye + is the world's first IoT smart radon detector that is used in connection
with web database based on WiFi. Therefore, RadonEye + is suitable for real-time
radon monitoring and easy to create Real-Time Radon Map. Manufacturer, Radon
FTLab provides web database, radon-net.com, which means the user can access
the data every time, everywhere by smart phone, tablet or internet connected
desktop PC.
The sensitivity performance of RadonEye + is like a standard instrument. It is 20
times higher when it is compared with other general customer’s radon detector, so
the measurement data is fast and precise. Radon measurement data can be
recorded within 1 hour with below
and the data will be updated every 10 minutes so the user will get to know the
diminishing trend of indoor radon level just within 30 minutes by ventilation or
window open.
RadonEye + has added temperature & humidity sensor and measurement time
recording and extended the measurement range to 255pCi / l.
RadonEye + offers free web uploading service at least 2 years.

Precautions
•Please, Measure in an environment free from vibration.
•Shock or disassembly will cause the equipment to malfunction and will not
be included in the warranty. (the unit will display “ERR” message)
•Abnormal data can be measured when using near a strong electromagnetic
radiation source such as high voltage transmission line, subway line, Wifi
transmitter(1Meter or less), microwave oven(1M or less) ('OVER' message)
•Use only indoors. No waterproof.
•Use the provided DC 12V adapter.
•Continuous use in an environment with relative humidity of 80% or
higher is prohibited.
•A warning message may be sent to the set mobile device when it is higher
than the set radon concentration.
•Proper operating temperature range is 10℃ ~ 40℃ (50°F ~ 100°F)
•The warranty period is one year after purchase.
- Accurate measurement value of the average radon level can be obtained when
the house is empty for 1 or 2 days.
- Reliable value can be obtained about 1 hour after start of the measurement.
- Radon concentration in the house is generally high at dawn and low at daytime,
so continuous measurement for more than 24 hours is necessary.

Radon ?
1. Radon is a colorless, odorless and tasteless radioactive gas.
Radon, a gas originating from radium which is generated by the collapse of
uranium in soil, is everywhere on earth. It penetrates indoors mainly from the
ground or building materials. The gases that cause sick house syndrome and
other noxious gases luckily smell. Urban gas and LPG were deliberately smelled.
However, radon does not smell nor can be seen. And no matter how many
years have passed, it is constantly released from the wall, ceiling and floor.
2. Radon is 8 times heavier than air and is easily concentrated in the house.
Radon has the half-life of 3.8 days and makes alpha decay. The alpha particle
emitted from radon has the smallest penetration power among the radiation
rays and can not penetrate even a single piece of paper, but its destructive
power is so great that the cells are damaged if they are directly impacted by
radon, even having a nickname of "silent murderer". This is why radon
detection sensor is absolutely needed in home.
3. Radon gas causes lung cancer.
Three causes of modern female lung cancer are passive smoking, ultrafine
particles and radon. When radon gas enters the lung through breathing, alpha
particles released from radon damage the lung cells. Since once destroyed lung
cells are not regenerated, prolonged exposure to high concentration of radon
gas will increase the likelihood of lung cancer. Therefore, the United States
RadonEye + provides Remote Radon Monitoring Network Service. You can
check radon value in the web browser by registering the registration key which
is given when you access the radon-net.com website when setting the app. You
can also check the local radon value at any time through Radon Map.

A : If the green LED on RadonEye Plus2 keeps blinking and Wi-Fi connection is not successful, please check if Wi-Fi password is entered correctly
and internet connection status of the Router.
2.4. If the message 'RadonEye Plus2 registration failed' is displayed when the button is clicked after entering the Wi-Fi information,
A : Smartphone should also be Internet-connected through Wi-Fi / LTE / 3G
Check the Internet connection status of the smart device and proceed with setting under this circumstance.
2.5. If other cases of setting failure
A : Check the Wi-Fi and GPS connection on your smartphone, then turn the device off and on and run.
3. How can I change RadonEye Plus2 wifi connection that’s been already set into previous wifi place?
A : If you have Wi-Fi in your environment, you can set it up again and use it easily by clicking ‘Main’-‘Sub Menu’-‘Network’
