Just a heads up on the differences between the different Temperature Control/Limiting/Protection devices available from China.
Due to not having anything really suitable to accurately measure the temperature, this is more of a comparative thing.
The set up was an IR temp scanner fixed securely in a small suction vice. It couldn`t move, vital for a test like this. The wood mod you see in the picture is glued to the worktop
So the relative positions of the coil and the scanner were the same for each of the mods.
There is a Magma fitted to it which again cannot move in relation to the temp scanner. A couple of leads are soldered to the 510 in the wooden mod and then a modified 510 adapter is soldered at the other end, which can be screwed onto a mod without disturbing the position of the atomiser or Infra Red Temperature Scanner.
All of the mods were set to 400F and tested one by one on the set up.
It confirms my thoughts on the IPV4 displayed temperature inaccuracy which is way out.
I have seen quite a few references to failed wick burn tests on the IPV4.
All of the other ones are fairly close to each other.
I think the way forward with these mods is to do the burn test on each mod and take a wick scorch temperature reference reading for that particular mod. Use that as your ref. Maybe start off at 50F below that ref and adjust to your taste without getting too close to the ref temperature.
I have to set my IPV4 at 310/320F to get a comparable vape experience to the other mods. But IMO each make should be treated individually. You will see that the numbers do not correspond to what you would expect, that is because you cannot use a cheapish infra red scanner to read the temperature with something as small as an atty coil.
It shows me that Kangxin were really on the ball, and very close to the Evolv chip, if they had included the initial ramp up the same as on the Evolv board it would seem they would be nigh on the same.
