@KeroZen Well reading random stuff on the internet often brings confusion/mixup of terms.. Just looked it up,and yes it seems that thermocouples are measuring the temp based on the raise of kinetic energy in the head.
The effect TC software is trying to mimic is one of a RTD not a thermocouple..
https://en.wikipedia.org/wiki/Resistance_thermometer
Resistance thermometers, also called
resistance temperature detectors (
RTDs), are
sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum, nickel, or copper. The material has an accurate resistance/temperature relationship which is used to provide an indication of temperature. As RTD elements are fragile, they are often housed in protective probes.
RTDs, which have higher accuracy and repeatability, are slowly replacing
thermocouples in industrial applications below 600 °
C.

So in the TUBO heater (and many others ) We still have the scenario where the Heater is the RTD itself

.
Among popular RTDs are the Pt100 and Pt1000 which are commonly used with PIDs.. Which are also known to have better accuracy then J/K type thermocouples,which are only used in temps above 600C ,because of their durability.
----------------------------
I kinda starting to suspect that TC software would deliver far better accuracy in most convection on-demand/ecig portables than a thermocouple,which only measures the temp at a certain point of the heater.
Imo until we dont see convection vapes adjust their temp according to what is happening in the herb chamber, this is as accurate as it is going to get
