Type: t-couple or t-resistor?
I was searching such a item or a complete iron unit in my town. I was surprised there's 2 types of them - with thermocouple (cheaper, commonly heated with Ni-Cr wire inside) and with thermoresistor/sensor - more expensive and probably with ceramic heating core.
One strongly negative review here IMHO is because wrong choice.
Stuff or owners please let us know what type is this one?!!!
To tell from just measure resistance between sensitive (red & blue) wires. Thermocouple has just several Ohms, while cold sensor may be 50-60 (or so, but never (while cold) <15 I think ). If in doubt, thermocouple generate voltage (mV) while the unit is hot (attaching a proper power supply to 2 other wires/ or by outer flame).
Thank you forwardly.

What is the heat sensor reading at room temp I know the heating element is 13 ohms
