It is a very wise decision to choose an active radon gas tester for your home. Radon levels can change at any time and short-term testers are no use when this happens.

Airthings Corentium Home 223 Review
The Airthings Corentium Home 233 portable radon detector is one of the finest active testers available. It is completely portable and operates using 3 AAA batteries. This radon tester has a European design and the company tested the device rigorously in Japan at one of the world’s leading test laboratories.
This is a high-quality active radon gas tester designed in Norway. Airthings has CERN scientists in the house that designed this radon tester from scratch. They wanted to create an accurate tester that was very easy to use and portable. They achieved all of these things with the Corentium Home 223 product.
Being portable you can use it anywhere in your home. There are no elaborate installation or setup requirements. Just place the device in the best location in your home, switch it on, and it will start testing. If you want to perform a short-term test you can do that. But this tester is best for long-term testing.
The LCD display will show you both the long-term and short-term averages which is very important. For the short-term average, you can see the number of days used to make the calculation. This device is very lightweight and so easy to use. You can start testing the radon levels in your home straight out of the box.
This model uses advanced technology to bring you the most accurate results. Dust, electromagnetic interference, and humidity affect some active radon detectors but none of these things will affect the Corentium Home 223. Although this is a radon tester for home use it has the same technology found in commercial testers.
There is no requirement to calibrate this home radon tester. It is fully automatic and just needs proper placement and turning on. Usually, the highest radon levels will occur at the lowest point in your home. But this is not always the case. With the portability of this device, you can test the levels of several different rooms easily.
How to use the Airthings Corenium Home 223?
There is a specific model designed for use in the USA that will measure radon levels in pCi/L. You can use this tester continuously for 2 years without having to replace the batteries.
After you switch on this radon tester it will perform a comprehensive self-check. The user cannot interrupt this essential check as the device disables all buttons and controls when it is testing. It will also self-calibrate. In fact, this advanced tester will self-calibrate itself every day.
The self-calibration element is very important as it ensures the most accurate results. If there is no proper calibration of a radon detector then the results can be wildly inaccurate. You are relying on these results for the health of your family so it scores very well in this respect.
You can use the LCD display for one-day and seven-day readings and you can also view the past history up to 12 months previously. This tester becomes more accurate the longer that you use it. Airthings claims that after 7 days of use, the accuracy is within 10% of the real radon levels and after 60 days it is within 5% of actual levels.
There is a USB port with the Corentium Home 233 and you can use this to download data from the radon tester and analyze it on another device such as a computer or a smartphone or a tablet device.
It is now possible to generate a radon report online using the airthings.com website and the results from your Corentium Home 223. There is a form on the website where you need to enter all of the essential information correctly, and you will receive a printable report via email after submission.

The Safety Siren Pro Series 3 Review
The Safety Siren Pro Series 3 is a very accurate home radon gas detector. The aim of this detector is to provide you and your family with the ultimate protection by alerting you when radon gas levels become too high.
Made in the United States, this active radon gas detector has EPA evaluation. You can use it to monitor and display both short-term and long-term radon gas levels. There is a digital display on the front of the unit which displays the readings clearly.
The Safety Siren Pro Series 3 is not a portable device. You have to plug it into a mains power outlet to use it. It is all set up for use in the United States market with all measurements in pCi/L. There is a threshold audible alarm that triggers if the radon gas level exceeds 4 pCi/L.
How to use the Safety Siren Pro Series 3?
Your product will arrive in a packing box with a user manual inside. Choose a location where you want to test for radon gas and then plug the tester into a standard mains outlet. On first use, you need to wait for the audible alarm to beep four times.
After the four-alarm beeps, the Safety Siren Pro Series 3 starts to measure the radon levels in the area where it is located. You cannot see an exact reading immediately and have to wait 48 hours for this. The first reading from the device will be a short-term result.
Although it is not a truly portable radon detector, you can test other areas of your home by simply unplugging it, moving it to the next location, and then resetting the tester so it starts measuring radon from scratch.
The Safety Siren Pro Series 3 is not very large but it is the kind of size where it could get easily knocked or moved around which could affect the accuracy of the readings. You can hang this radon detector on the wall to keep it out of harm’s way.
It will take at least a month of continuous testing to get your first long-term average radon level result. This is the default reading on the digital display. If you want to see the short-term reading then you will need to press a button for this.
Like other good active radon detectors, the Safety Siren Pro Series 3 will perform a self-test every 24 hours. This model updates the results it measures every hour and it is able to store the data for as long as five years.
It is pretty easy to use this radon gas detector and other than locating it in a safe place, plugging it into a mains outlet, and switching it on there is not much to the setup either. We found the results to be very accurate for both short and long-term measurements.
You have the option to turn off the audible alarm if you want but we recommend that you keep this turned on. The only issue with the alarm is that it will sound every hour that the radon levels are above the threshold.
