I just received my data logger and I'm trying to understand what its telling me. It said to turn it on and it would calibrate itself. This is the room that my 5×5×8 tent is in.

Its telling you that the room temp is 74.1*F, your Relative Humidity (RH) is 26% and that the concentration of Co2 is at 3290 ppm (parts per million). I dont believe the meter is calibrated yet on the ppm though. Average room ppm for CO2 is around 400-900. Ideal range for most Co2 setups is between 1200-1500 ppm. How long did it say in the directions to give it to "self calibrate"?

That's what I thought was odd as well. It says to plug it In and it does a countdown from 10. After that is says it requires "no initial setup or calibration"
My tent pulls air and vents into the same room.

Is there a decimal point missing between the 9 and the 0?
329 sounds reasonable but 3290 = no way

PPM indoors can get very high. Many older houses don't have a fresh air intake in the central air system. This combined with people exhaling, pets, gas ranges and the like can make for some really high indoor readings. Indoor air quality is enhanced by having a fresh air intake on a central air system.
3290 is dangerously high.
anything over 1000ppm co2 and I want supplemental oxygen available nearby, and a spotter outside just in case I get dizzy.... my former employer gave me confined space training....
Over 2.000 and you need hazmat type gear..... 3290 this guy would be passed out on the floor.... there would be federal investigations as to why he's about to die...
if you are pumping co2 into that room without a monitor and you're getting this reading open the damn windows quick.
I agree something's off on that...

I dont think so. It's not super clear.

Well I took it outside and it seems as if it steadied out at 650 ish. It reached 488 at its lowest and 708 outside after 15 mins. Its 18°f here In michigan

Others have high levels indoors and it's not desirable. Id trust this meter (I have two and they are awesome and match what my CO2 controller reads).
Do you have a carbon monoxide alarm? You may have issues with your furnace if it's gas or propane.

There is no decimal on that unit for CO2 numbers.

But could have the same cause. I am saying that his furnace may be malfunctioning and putting CO and CO2 into the home.

It went right back up to 3500

If the OP gets dizzy in the house that's a serious problem.
1500ppm is fine for humans and represents the upper limit for CO² augmentation.
The best results seem to come from intermittent supplementation; keep the normal level about atmospheric, then boost the level up to your desired Max once or twice during the lit portion of your cycle.

You should get the furnace checked out. Those levels are not good for your health. I highly suggest having a pro look at the furnace, at least get a CO alarm to see if you have high carbon monoxide levels as well.

Thats not a safe range to be living in if it is indeed accurate. I'd second renfros suggestion to get a carbon Monoxide alarm for your home and have your heating sources inspected.

My house was built in 2007. After talking to my father, he said that the entire house is relatively sealed up to protect against the frigid winter air. I opened a window. Opened it only 7 inches but it's a 5ft tall window
