Safety Siren Pro Series 3 Digital Radon Gas Detector

How far off were yours from each other when tested side-by-side?

If you can believe it, I never tested both my radon detectors side-by-side before. The other day I took the one from upstairs and put it downstairs on the other side of the basement from the other. One reads 3.0 and the other reads 4.5 so not I moved them side-by-side to see what I get as a reading.

I just moved them together today. I should reset them and wait 2 days. :?

I didn't reset mine, I will just have to leave them there long enough to allow for a complete change.

I did not reset the two unit and the reading were dropping over the last week but they were off 6.6 and 18.7

I just checked mine and they say 3.2 & 4.5 so I will keep watching them over the next few days to see any change.

I just checked my two radon detectors again and now the one is still 4.5 pCi/L (as expected) and the other one that I moved from upstairs to the basement (still sitting right next to the other one in the basement) now reads 4.4 pCi/L so I am impressed! I will give it a few more days to see if it will reach the 4.5 level. I have no way to prove 100% that the true level of radon in my basement is 4.5 pCi/L but I can safely say these two radon detectors are calibrated the same.

The test results are in from checking to see how close my two radon detectors are calibrated.
