Has anyone checked accuracy for this product?

The short answer is not yet. The unit has been positioned in the basement since early December 2013. If the long term average is above the "4.0" at the end of March 2014, I will have an out side firm radon remediation firm come in and test our basement with their system. Until then I will not have a comparison. The (1) day, (7) day, and long term values fluctuate as time passes, but they seem reasonable. Sorry I couldn't help more.

As far as I know you don't. I have two other oxymeters and have taken overnight tests with professional grade recorders and my meter reads accurate out of the box when cross-referenced with the other meters. It is important, at least for me, to remember I can vary up to 5 points depending on what finger I use with any meter. Anyway, my meter came accurate and didn't need calibrating so I never looked in to it.

Mine seems to give accurate readings...instruction sheet in box is fairly clear and easy to follow, even for an old timer like me.

It's generally accurate to a couple meters from what I can tell. For example, if I run out on one side of the street and come back on the other side, that's obvious when I review the run map.

I would say it is fairly accurate. However, I don't really let my motorcycle battery get that low to really determine how accurate.

I don't understand the question, but regarding accuracy of readings, I have no other calibrated instrument with which to check the accuracy of the readings displayed with this product. Generally, they appear to be reasonable based on published noise decibel readings.

flat out we havent a clue how accurate the number is. but the one I bought is consistant. the calibration knob is used to get your SWR its not used to calibrate the meter

Yep! But I have never checked if it is accurate. Last, the temperature is adjustable.

I just got it and I've only used it twice, but yes it's accurate...although one of those times it did take me on a slightly longer route which used wider streets. I assumed that was by design because I told it I was driving a 40' motor home.

I have not compared the accuracy of this product. However, just today I tested my filtered water and then decided to test the water as it came from the spigot. The water from the spigot showed over a 2.0 reading. I check my filtered water periodically. If the reading is near or above 0.6, I then change the filter on my pitcher. I've been very pleased.

Mine is pretty accurate. I haven't mic'd it because there's been no need. Never had a problem

I have no way to verify accuracy since I don't have nist traceable standard weights. Precision seems OK. I have noticed that the scale sometimes doesn't want to zero. I'll turn it on and it moves away from zero (I have seen it go higher and lower). When it does this the zero may wander as much as 10 lbs. Eventually the scale stabilizes. I have not contacted the mfg. I find this annoying but am willing to live with it since it rarely happens.

I would say it is fairly accurate. I compared it to my more expensive Radio Shack and the numbers are very comparable.

I have not. Without comparing to a calibrated gauge, you won't know which has gauge is actually the accurate one. What I like about this gauge is that it gives me percise consistent results.. Hard to tell how accurate they are however like I mentioned.

I do not know. However it is as accurate as the device in my doctor's office.

My impression is that it is only accurate to tenths even though it shows a hundredth place. Since my uses do not require greater accuracy, I haven't really checked it out.

My answer would be a big YES... it seems very accurate and I often compare it to the one my Step-mom uses daily at her Hospital job.It's consistant within 2 or 3 percent. My husband and I are in our late 50's and we both use it once every morning...again after our daily workout at the Gym...and again a few hours after the Gym workouts. six times a day and it has never failed to give good solid readings.
