The PHFS-01e is the first low-cost heat flux sensor on the market. It has minimal thickness while still maintaining excellent sensitivity. Copper, or other metal, foil cladding encapsulates both sides of the sensor to make this sensor both robust and reliable.
- R&D of heat transfer components
- Energy efficiency of thermal systems
- Heat transfer education
- Wearable technology that detects calorie burn.
