Are we positive the readings are accurate? I have now tested the first floor of the house and am getting a reading of 7.5 pCi/l.

There is a certain amount of liability I would take by answering if your machine is accurate. I would suggest you do a charcoal test next to it to compare readings. Your first test that come back over 4.0 always makes you second guess any machine.

I have an older monitor upstairs that's not portable.....plug in type & side by side, they both give the same readings. So I take it that either both are wrong....or....both are correct. The readings fall in line with the governments upper normal values for my area. Hope this helps. Sorry I couldn't give you a better answer.

I checked the accuracy by using a charcoal canisters {2 separate tests} from a good, local lab...so I trust the lab results were accurate as benchmark. The meter read about 45% higher. The canister was 9 and meter about 13 on one test, and appx same on second test. So I just adjust divide my meter reading my 1.45. So if meter reads 2....divide by 1.45=1.38. In other words....if you increase 1.38 by 45% you have 2.00.

We had a professional test done when we had a mitigation system installed and they were within a tenth or two of this device.

The manufacturer claims a +/- 5% accuracy. My experience is that at least 7 days is needed to obtain a meaningful average. I actually use 2-3 weeks. Variations can be expected for different periods in the year as well.

I had my below ground theatre tested with the mail in it was 18pci/l and thats what the meter read as well. After installing simple crawlspace ventilation (which came back at 40pci/l), 6 months later my long term readings dropped to 1.7ish, the hourly still goes up to about 2.9 in the rain but I think it's accurate enough to be within a1pci/l at the worst.

My experience ove the yer and a half has shown that the unit measured high over the first 7 days and then it goes up or down depending on the levels. 5.02 over 12 months.

The readings are on the machine. As for quantities to add depending on reading, your pool store should be able to help you out. Otherwise just add some of what is needed and test again.

what's the certification on your power supply? (80+ bronze, silver, gold, etc..), 750 should be more than enough by far, but if the power supply unit is sketchy then it could be not performing anywhere near what it theoretically should be. also, anti-surge could be related to your electrical setup, what do you have the tower plugged into? does it trip the circuit breaker or does only your tower shut off?

Here is what I found on the web... Clean Power <7% THD. Not sure if it's @ full load or not.

Seems to be accurate. Sampling time is several times per second. No idea about how reliable, when I was on the O2 the reading was higher than when I was not.

Sorry,no idea. I simply run it at max. I doubt there's any downside so long as you don't peer directly into it. Good luck/stay happy.

Hello,Mine is measuring 3.88 on average. If I were you I would reset and then see where it goes. Twenty five sounds outrageously high. I would check it again then if the numbers are still that high I would buy one of those radon detectors that you mail in to compare the readings. I love the unit I bought as I can move it to different places. I have reset it a few times but overall it seems to be working quite well. I really hope those readings are bogus and that it just needs to be reset. If not you will have to have a system put in for remediation.

Yeah, this is seems common, they aren't exactly a "high speed sync" solution. 1/160 seems to be the best speed for reliability

Mine is running 82C under full load. I mine dogecoin with mine when I'm not gaming. This is also with an older GTX 570 right above it.

Hi Lawrence, fitted this card 4 days ago and no its not true, in my rig its not at all loud.

Agree with the comment about doing things just right. Mine is very accurate. I will say I messed around with it a bit in the beginning to see what would make it go astray. Generally speaking though it is very accurate. I have had no problems.

I don`t know what is wrong... my starts in 390. Are you using the right voltage?

Yes. But you will be better of calling the MFR and get the machine reset to give you just one reading. The time that lapses between the 3 reading is not enough to call it average.

I have also run more like 75' of cat5e cable and mine is working fine. I would trust the long cat5 cable more than the wireless link. Tech support's 10' comment was off-base.

I am not familiar with that reading. My unit has worked like a charm. I would suggest that you go to the vendor's website. Maybe someone else has experienced something similar. Good luck!

Mine seems fairly accurate yet sometimes takes 4 or 5 tries before giving me a reading. Also, very occasionally I get a "high" reading (like 156) that I know is wrong. So I just wait a minute and re-check. This happens very on very seldom occasions.

I purchased this to check for continuity. I am not sure how accurate the resistance readings are.
