Frequently Asked Questions for Corentium Home 223 Airthings Radon Gas Detector
Q1.How many counts per hour does this do?
Answer: The Corentium Home will provide 1 count per hour. After 24 hours, your short-term average will appear, showing the last 24-hour average of counts. Once an hour, the short-term average will be updated with the new rolling 24-hour measurement. After 7 days, you’ll be provided with the 7-day short-term average, which will be updated daily.
Q2.Does this meter give instant Results?
Answer: No! But this feature wouldn’t serve the purpose anyway. Radon levels vary hourly depending on seepage rate and ground source depth; thus, the average per day over several days is the most accurate value. This meter assesses the average per day and over seven days.
Q3.How can I report the findings to my client as a Home Inspector?
Answer: The Home has an online tool that generates a Radon report with the long-term average by completing an online form with the details from your device. As a Home Inspector, they do offer their Pro, which is meant for professionals. You can check this article.
Q4.Are the batteries supposed to be left on until they die?
Answer: Yes, and then change the batteries. The battery’s long life serves its purpose well. You can leave it on continuously to get continuous measurements. It’s not mandatory to leave it on. You can take it to different rooms or houses by pressing the reset button with a bent paperclip, then start re-measuring.
Q5.Is radon an issue with slabs, too, or just basements?
Answer: Yes, slab dwellings can have radon. But without a basement, you’re less likely to have an accumulation problem. Radon is heavier than air, so it pools and collects in basements and crawl spaces, and it can also seep up from sumps, drains, and cracks from below. A house can also act as an excellent big chimney, drawing gases upward. The readings range from 0 to 10 picocuries/liter on the primary floor, with all windows wide open to the outside. The barometer goes up and down and rolls by from weather systems, and from the utilization of phosphorus fertilizers by nearby farmers — it’s very interesting to watch
Q6.How can you check the primary reading?
Answer: The first reading appears automatically after 48-72 hours.
Q7. Do you need to reset the machine to place it in a new location?
Answer: Yes, that is normal. When you reset, it will keep flashing hash lines on the screen for a while
Q8.How do you produce the report?
Answer: To generate the correct report, all you have to do is:
- A measurement duration of at least 30 (full) days. Shorter measurements do not produce a report
- of the serial number (S/N) of your monitor (found on your rear side Corentium Home).
- The number of days measured (press the MODE button 1 time to get the number of days measured)
- The 4-digit code can be retrieved by simply clicking the MODE button 2 times. This is often important: this code is exclusive and directly associated with both the Radon levels you enter within the online form and, therefore, the length of your measurement. Please confirm to enter this code correctly; otherwise, a report can’t be generated.
Once you have entered this information correctly, along with your contact details and the building where you performed your measurement, you can quickly generate your report.
The report is generated and available to download as a PDF.
Please note that the above information is directly taken from the official website.
Q9.Does the device not transmit any data wirelessly?
Answer: The Corentium Home is a stand-alone device that does not transfer data wirelessly and only displays measurement information on its digital display.
Q10.What is the shortest amount of time you’ll do a test with this device?
Answer: Professional testers need to be used for a 48-hour test. For this home unit, it should run for at least a week to be somewhat accurate. A month would be better.
It will have a 20% fluctuation for a 48-hour test. The 7-day test should have a 10% fluctuation, and the 2-month test should have a 5% fluctuation. If the fluctuation ratio exceeds the specified limit, contact support for help.
