Fixed it.
Look, I have several very high end Thermometers - Surface, Air, fluid, Thermal to mention a few. All have some very sophisticated internal components. The Probe tip is the END Game, not the casing. The Coil is the working component in the dna Temperature Control, not the Atomizer.
To say otherwise is simply sales hype. Fire a coil directly off the dna +/- connections, even without an Atomizer and the dna should attempt to control Temperature of the coil. Agreed?
Pedantic and meaningless distinction. You are making bad claims and supporting them with irrelevance. Whether I said coil or atomizer is insubstantial. The point is that the device does in fact measure and control temperature.
What I think variable temperature would do would be to allow me to nudge coil temp up or down like I currently can nudge voltage or watts up or down. What the DNA chip does is REDUCE power IF the coil reaches the MAXIMUM temperature you've set (which it calculates by measuring the resistance and doing a conversion based on the properties of Nickle wire - not by directly measuring temperature).
Not sure what you think every thermometer in existence does, but "directly measuring temperature" consists of monitoring the change in something else, from resistance to the physical expansion of a liquid such as mercury.
There IS a difference.
Let's say I want to vape at 400 degrees.
On a DNA, I set the temp to 400 degrees. But I'm at 20 watts. And my 20 watts is only producing 350 degrees. The DNA chip is happy with that - I am SETTING the watts, and LIMITING the temperature.
Variable Temp would (hopefully) adjust power as necessary to quickly reach and then maintain my 400 degrees.
You can simulate this with a DNA chip I suppose, by always having your power setting too high - so that the temp limit always kicks in...I'm not sure if that's how people are using it, but I don't think so. I think people who like it are just happy when the temp kicks in and protects them from burning a wick.
That is a nice feature. It's just not the same as selecting a coil temp to run at.
There is not a meaningful difference. Within the desired operation of an ecigarette, this is how you want to control temperature, you don't want it to idle at vaping temperature. Every temperature controlled device in existence has the same characteristics, it won't hit temperature if there isn't enough power to hit temperature, but it will try. The DNA40 does just what you said, it adjusts power as necessary to quickly reach the set temperature, it even goes above set wattage.
