A ceramic sensor blade is used inside the earlier versions of the IQOS blade holder (IQOS, IQOS 2.4, IQOS 2.4+, IQOS 3, IQOS 3 Duo, and IQOS 3 Multi).

This electronic heating blade in the IQOS blade heated tobacco holder simultaneously heats tobacco while monitoring the tobacco temperature to ensure a consistent taste experience and to avoid burning the tobacco.

In PMI's IQOS ILUMA heated tobacco products, instead of a blade, we use induction technology.
