Airthings Corentium Home Radon Detector 2350 Portable, Lightweight, Easy-to-Use, (3) AAA Battery Operated, USA Version, pCi/L

I did a charcoal test and found my radon to be at 3.97 thirty years after buying the house and having a radon system installed before we moved in. Over the years we added a third sump pit in the basement and the covers on the other 2 were mostly gone after all the pump changes.I bought one of these after seeing them to see if I could get some continuous monitoring. After the startup and a couple days later it came right in at what the charcoal test did. I watched the radon levels go up and down a little o the long and short term testing being variable with the amount of activity and air movement in the basement.I had the original company come out and reseal all 3 sump pits and watched the radon levels go down. I am now at .70% after the cover replacements. This little unit is a good peace of mind.

from all our previous information prior to purchasing this radon detector, we had significant reason to believe the area we wanted to test had higher than allowable levels of radon. this detector shows that. I cannot attest to the accuracy, i have nothing to compare the readings to. However, as i move the tester to different areas, the readings change as expected. I was going to install the definition sticker to the tester but the tester did not come with the sticker. this is one where because of the missing sticker i would have given less than five stars, however, only slightly less

I like being able to see where my radon levels are. This works great. You get to see one day, seven, and long term readings. Great peace of mind. Good price.

Works great for monitoring Radon in your home !I went & bought two to check different parts of the house . Priced right & seems to be good quality. It’s 2 months now !

great monitor for the cost , had to exchange it , the first one had a bad display but the new one is working great and its s nice thing to have around if you live in an area with alot of limestone under your house ! radon killed my mom and its nothing to ignore it will kill you!! test your house

This is a handy item to have to continuously monitor radon. I wanted to check different areas of my home at different seasons and this was most economical. The one time tests that get sent in didn’t seem to have great reviews - they get delayed in the mail or something. With this, I see results quicker and I can monitor at my convenience.Definitely would buy again!

It works really well. I bought a new radon pump and just watched the radon levels fall.

Works great
