Doc I like the vids usually, but this one is all over the place with bad info that could get someone killed. OSHA, NIOSH, and ACGIH all demand exposure limits of 25-50ppm over a 40hr work week; you're saying 100ppm "start to worry". You should be worrying way below that level. You say at 800ppm dead in a few hours. GROSSLY incorrect, you're dead at 2hrs max and likely under 1 hour. Then you zero the meter while it has a 15ppm reading and no explanation. So that's either a poor quality meter, you don't trust the 15ppm). Or you trust the meter but don't care about 15ppm, which is an odd flex. But the way you say zero it to your shop, that's not how CO works. You don't zero it to the environment that feels good. You zero it to a zero environment. Feels like I just witnessed a "3.6 roentgen, not great, not terrible" moment. This vid shouldn't be published, and your incompetence on this topic is going to get someone killed.
I nearly died from CO and CO2 poisoning, so I feel exactly the same as you Matt. I am constantly stressing on our channel to people that any number above 1 should be of concern. Most all CO detectors that hang on a wall, won't even go off (Alarm) until at least 35-50ppm, and that is contingent on about 15-30 minutes of continuous levels - which is extremely dangerous because the levels could drop a few points within that 15 minutes causing the timer to start over, and if the levels continue to fluctuate, the alarm may not go off for days or weeks of constant exposure of an average 15-50ppm. I would never ever recommend a CO monitor that hangs on the wall or and especially the ceiling, because in colder temperatures, the CO gets heavier than air and go to the ground, and at warmer temps, the CO is lighter than air, and goes to the ceiling. CO and CO2 are very very dangerous gases that should NEVER be taken lightly. It is only when someones life is lost or a child is lost, that it is taken serious, and that just should not be. I was surprised that this guy said don't worry until it gets higher than 100ppm - especially when he had a friend that died from CO poisoning. Please everyone always remember, - absolutely anything above 1 on a CO meter that stays there for a few moments, should be taken very seriously. Sometimes a CO monitor will go to 1 or 15 because a CO monitor can be tricked by paint fumes, alcohol etc., or other gases like Nitrogen (I am getting ready to do a video that shows a CO meter going bonkers around Nitrogen - as charging lead acid batteries will discharge Nitrogen into the air and cause a CO meter to go off the scale, so CO meters are good for that as well), but most of the time (if there are no issues), a CO meter may jump to 1,15, or 25 (triggered by paint fumes, perfumes, alcohol etc., but for only a second or two, and then go right back down to 0. If your digital CO meter, goes above 1 and stays there for more than a minute - something is wrong and should be looked at, and PLEASE do not EVER wait until it reaches 100ppm before acting, and the reason for that is - that you can actually fall asleep at 100ppm, and if it continues to rise after you have fallen asleep, - what happened to this guys friend, can and will happen to you or a loved one, so please be careful about CO numbers, and take them seriously. You want your CO meter to ALWAYS read 0. If your meter stays at zero all the time, also make sure that you test your meter from time to time by lighting a piece of tissue paper and blowing it out, and then let the smoke engulf the meter, and that will cause your meter to go nuts until you take the smoke away. So thank you Matt for your thoughts, and also it is great! to know that there is at least one other person that feels the same as I. Carbon Monoxide IS VERY DANGEROUS stuff, and reading and believing the manuals that come with wall-hung monitors will cause someone to become complacent, - and complacency kills - DEAD....
@@Outside-In. Ironically I wrote that comment about 2hrs after being dispatched to a CO alarm. Homeowner said just a malfunction and wanted to cancel fire dept response. We came anyway - as we do for all CO alarms. My meter hit 80ppm at their front door, I went on air, and meter read 450ish ppm before I hit bottom of the basement stairs and the meter maxed beyond its calibrated ceiling. My meter was climbing by 50-100ppm about every second. It was around 1,000ppm in the basement. Where the 3 kids had been playing just hours earlier. Their CO alarms saved their lives. The parents cavalier attitude almost killed them. I have personally witnessed/responded on many similar alarms, and most any fire, medic, or cop will have the same stories just different cities. The one thing they all shared in common, was the same cavalier attitude and overconfidence we're seeing in this video.
I have the TopTes PT520A gas leak detector (propane, natural gas, and other combustible gases) and just used it this past week after replacing the thermal fuse on my gas dryer. I recommend the TopTes products. Good feature and price value. Now, I guess I'll look at their Carbon Monoxide detector. 😋
I wanted to use this for the interior of my car to detect exhaust manifold leaks. I was going to see if exhaust fumes (i.e. carbon monoxide) were leaking from the manifold into the cabin. Are you saying it's not good for that because of all the other gases that come with the carbon monoxide from engine exhausts?

Thanks for taking the time to explain this thoroughly.

Great product I do believe I need one.
Not a bad price either.
Thanks Doc

Great video thanks👍🏻🇺🇲
Ahhh… CO and the Krebs cycle!
CO = Carbon Monoxide.
CO2 = Carbon Dioxide.
