What might it be? I've been searching the internet, and this site, for an answer to the question. It's hard to find anything that's both definitive and plausible.

I've found answers that vary from 'about body temperature' to 1800 degrees C. The answers are confused however, and some are simply confusing dry coil temp with reality.

I'm aware of course that it will depend on a number of factors: Power in the coil, draw speed, fluid mix/viscosity, how far the coil is from your mouth, wick...

I'm pretty sure that it's lower than the temperature of inhaled tobacco smoke, but I want to know more. I would have thought that someone at sometime would have at least made a measurement; I can find nothing.

Can anyone help, or must I figure out how to build some sort of test rig with a thermometer, if indeed that would even work?
 
Vapor at 1800 degrees would remove your tongue. :) Besides, to get it that hot you'd melt the Kanthal wires, and that's never a problem with our devices.

It feels like it's about blood temperature or a little lower from my bottom coil, I've noticed top coils feel a lot warmer.

Temperature's going to vary by the ambient air temperature, resistance, battery power (if unmoderated), and even the current air pressure (so altitude as well). You'd probably need to jigger up a temperature sensor and test under a variety of conditions to determine the normal temperature range of the vapor for your device and your locale under a given set of conditions.

Don't quote me on this, but I always figured a stinky would burn at about 700 degrees in temperature - I'm sure google will prove me wrong...BUT...from my experience, the vapor is far lower in temperature than a cigarette.

I'm assuming (a fool should never assume, but I do...do the math) that if a cigarette is burning hotter then the smoke is hotter than vape.

How's that for science after a beer (or three)

:D

I'd not worry about it though, but sure, a thermometer might work.

It will all be variable though, not sure how you could validate any results as we all use different -everything- vape wise. I've not met anyone using the exact same heads/mod/juice I use so don't know how worthwhile it would be. Would certainly be interesting to know your results though :)

For a top coil tank it's slightly above the ambient air temperature. Usually within about 5 degrees or so. For a bottom coil it can actually be below ambient air temperature as the condensation effect of the vapor draws heat from the surrounding air.

Try this one. Take a breath and exhale into your hand. Then, take a puff of vapor and exhale that into your hand. Do you feel a difference?

You are extremely close: What Temperature Does a Cigarette Burn? - Ask.com

So 700 C to 900 C per that, assuming it's accurate. Off the cuff, it feels about right.

I'm assuming (a fool should never assume, but I do...do the math) that if a cigarette is burning hotter then the smoke is hotter than vape.

It would depend on how much heat it loses as it comes down the tube, but I certainly remember the last few puffs of a cig were hot to very hot. There was a touch of adjustment to vaping as the vapor was never that warm.

It'd be fun data just to see. But you're right, one person's results at a given voltage won't match mine using different equipment.

I remember sharing ciggies at school and if you had "last half" (which was always a con as it was never half, them last few puffs burned!

If the coil in a e-cig/mod/tank whatever, burned to 700-900 degrees there would be a lot of melted plastic I'm guessing. I think it's a safe bet it's a LOT cooler on most levels - given most will cut out after 10 seconds, you'd have to really go for it to get close (if it's even possible)

Well on a top coil it can be warm, and on a bottom coil it will be cooler; when my setup works really well, the exhaled fog feels cool on my face if I'm walking in the sunshine;

get a silicone drip tip, drill/punch a hole in the side, and stick the tip of a thermometer in it?

I picked up some of these yesterday to use instead of the metal ones. Unless someone beats me to it tonight, I'll try and buy the thermometer tomorrow and give it a go. I'll post the range of results for a couple of diff resistance coils at diff voltages of course. Good idea man.

I guess I'll have to find an analogue smoker, and convince them to stuff the thermometer into their filter too; that's going to be more tricky.
