The HF-01S is a small size standard plate type heat flux sensor. It is an ideal option for research and engineering applications as well as manufacturing control and monito-ring processes. Manufactured in compliance with standards ASTM C1046 and ISO 9869, EKO HF-01S includes a built-in thermal guard and two facings to ensure an even heat flux distribution and therefore a reliable measurement experience.

The unique combination of small size, thin body, and high sensitivity, makes this sensor a perfect choice for accurate measurement of heat flux, even in low heat flux conditions. Thanks to the thin body and high thermal conductivity, the thermal resistance is kept very low to minimize the heat flux disturbance on the surface and avoid edge losses.
