We want to provide you with long term and short term averages with the most accurate readings every 24 hours. See everything you need right on the display.

Corentium Home is a portable device and can be moved from room to room to measure radon levels Peace of mind knowing you are safe from the dangers of radon gas.

Review: Reliable and accurate radon meter, highly recommended - I purchased the product over a year ago from desertcart and it has been performing perfectly. I live in an area which has a granite bedrock and as such, has higher than normal radon levels. I found the Corentium Home to be very easy to use. It takes a few days before a relaible radon reading is obtained but the longer you measure, the higher the accuracy of the measurement. For the technically-minded, it uses an alpha scintillator to directly measure the radioactive decay of both the radon and the radon decay products. Battery life is very good (I'm still using the original set of batteries) and product support from Airthings has been excellent. If you are going to buy a radon detector, then this is definitely the one to choose. The only criticism I have is that it is not supplied with a stand.
Review: Excellent product and support - I purchased the detector for domestic use and it has worked very well, measuring both the long and short term averages of the prescence of radon in different locations around my home. Latterly an error code was displayed and I therefore contacted the company resulting in a replacement being provided. I am very satisfied with the Corentium Home and the support provided by Airthings.

## Questions & Answers

**Q: is this dispatched from the uk/**
A: Yes

**Q: Can you just use the monitor by reading on the monitor itself without registering on line?**
A: Yes - although account needs to  be taken of the fact that there are wide fluctuations with time of the radon concentration in a home, depending on weather conditions and upon whether windows and (internal) doors are open. I have found that a radon fan and a radon sump together enable the radon levels to plummet dramatically. I normally use an average reading over several days, although shorter intervals between taking sets of readings can be very interesting (- especially if you like stats/numbers!). I found this detector to be extremely useful and ultimately, of course, its use is certainly no bad thing from a health perspective.

**Q: Did anyone have theirs delivered with the batteries already installed on?  mine did, and i'm wondering if the one i received was a return/refurbish.**
A: Hi there,

Thanks for your question and interest in Airthings! David Harrison's answer is correct - this is how they are supplied, new, with a small plastic tab to remove to complete the power circuit. 

All of our Airthings products come with batteries, and in your case, the Corentium Home comes with 3x AAA batteries which should last up to 2 years. Simply replace them with new alkaline batteries when they need changing. You can read more about the lifespan of the Home in our help center https://help.airthings.com/en/articles/3669173-home-what-is-the-lifespan-of-the-home.

**Q: Mine arrived without batteries and no pull tab, why?**
A: It could be that Amazon shipped you an open/used device, I would get in contact with their customer service to have them exchange this for you. All of our monitors will come in a sealed box with batteries and a pull tab.

### ⭐⭐⭐⭐ Does what it says
*by J***E on 21 April 2025*

Good if you check daily but a full annual report doesn’t seem available. The average is helpful but I’ll need another to see what’s going but good to have. Easy to use
