[Standard Type] I want to measure heat flow.

This is a standard thermal flow sensor that can measure the amount of thermal energy passing through the measurement surface (W/m²; thermal energy passing through a unit area) and its direction*. *The vertical component of the thermal energy input on the sensor surface. No power supply or amplifier circuit is required, and measurements can be taken immediately if there is an environment capable of voltage measurement. You can choose the size of the detection part and the length of the cable according to your application.
