I just received my FLIR ONE Thermal Imager for Android today.

This is my BGE a few hours after I cooked dinner. Wow they really hold the heat.

thats a cool feature!

Very cool device!

Your mission, should you decide to accept it:
I've always wondered if, while doing a low and slow with the bottom vent cracked but the daisy wheel completely removed, if some fresh oxygen doesn't come into the egg, from the top.
Don't know if your cool app would show that or not, but it'd be something to try.

Can't really see drafts. Air is too low density, not enough thermal mass (like a heat sink) to stand out. 

Tried finding some drafty spots in the basement. No go.  See also the mythbusters "is a f*rt visible on FLIR" episode

Fun fact: i designed two houses for an exec at flir. Back 25 years ago. I should have bought stock. 

that lake house i posted once was his

It's ALIVE. IT'S ALIVE!!!!
(37C = 98.6f, same as normal body temp)

This one has MX Technology overlays two images and makes it more useful.

Yes you can use it to find drafts it is best to do it when there are big difference between the areas checked.

Home energy auditors use these to help them do their jobs.

@Botch

I am not sure what it will show but I will give it a try.

you can't spot drafts themselves where there is a minor difference in heat though.

i used one to audit my own house.  you can see areas of heat loss and missing insulation, but you can't spot an incoming draft of 45 degrees in a building at 68.  you can see where that heat loss has cooled the neighboring materials though, sure.  but you don't watch flowing air like seeing a cold river.

the question was whether you could see airflow into the egg during a low and slow (at the top vent).

FLIR calibrates and tunes their instruments for different conditions, so they might have one where you could achieve that level of discernment.

when Katrina hit, they made (or were considering making) some where insurance adjusters could determine where water damage was behind walls.  it required fine tuning the range, which affects what it does at other temperatures (from what i understood).

my point re drafts was : it doesn't see the wisps of air flowing , it sees where the moving air had removed (or deposited) heat. IIRC correctly, for their standard range their devices investigate, air itself doesn't have enough mass to contain enough IR energy to be seen itself. 



that's the sill from the exterior.  you can see where heat is escaping, because the fieldstone foundation is hotter, but you can't see the air itself flowing, or go inside and watch the cold air (the draft itself) coming in through another crack. 

maybe you can fine tune the range, i dunno.  but MB showed it wasn't possible to see air unless there was a significant difference, like the cold blast from a can of electronics duster

Glad it can't "see" air currents.  Would make it a pain to see the object you wanted to look at.

Yes we are saying the same thing I agree with you that is why I said you can use it find a draft I did not say you could see a draft.

Want to join me on a BIGFOOT Hunt?   Sure could use the FLIR support!

This Flir might be a better pick rather than a close-quarters version when hunting BigFoot:

I've used some of the best thermal imagery units from Flir. They are bar none the best I've used. Used on dual 800A MDP, glycol heat rejection units, Chillers, etc.  At the time the test instrument was close to $3K
I saw the unit you're discussing about a yr ago at a distribution HVAC/R show for techs.

We are looking at a FLIR unit for the boat so we can run at cruising speed in the dead of night.  $8-$9k  is a bit tough to swallow. However, if we were to hit something, $9k would seem like a bargain - and that would be if we did not sink. 

Super cool technology. May not be new at this point, but still super cool.

We have used the FLIR cameras for years to find hot spots in our electric substations.  When we are not using it, our Marketing Department borrows it and does "home audits" for building contractors.  Remarkable equipment.  The latest camera we purchased was the FLIR T1K HD, and cost $39K.  It's a blast to take out in the woods at night...you can see rabbits, deer, and lots of critters running around!

That must be an amazing tool.

The one I have is only $249 but a few years ago one this good cost thousands.

So they have really came a long way.

But it would be fun to watch a fart!
