Heat Flux Data Logger for Ovens

Are you experiencing uneven product quality, moisture retention, or inconsistent baking in your commercial bakery oven? Consider the heat flux data logger from Reading Thermal and our other state-of-the-art sensors and sensor arrays.

Reading Thermal, a division of Reading Bakery Systems, has focused on the commercial baking process for nearly 30 years. We manufacture the SCORPION® 2 Data Logger, which travels through the oven with your product(s), enabling you to monitor actual in-process conditions and get the information you need to correct any problems during baking and maintain the best process control.

This powerful diagnostic tool has become an industry standard for understanding and improving your proofing, baking, cooling, and freezing processes.

What is Oven Heat Flux?

Heat flux is the rate of heat energy that passes through a surface. It is the best way to determine oven performance when baking in terms of the product. Bakers often use heat flux profiles when they want to produce the same product on different lines or when transferring product from one line to another. The lines will produce the same product when the heat flux profiles match. The SCORPION® 2 Heat Flux Sensor measures heat fluxes – both convective and radiant – at product level and presents the results in Btu/hr·ft2 or W/m2.

Why Is Heat Flux Profiling Important?

The characteristics of specific products are defined by the amount and type of heat applied to them while baking. The differences explain why one oven bakes differently from another. Analyzing and controlling these differences is essential to understanding how the finished characteristics of your products will be affected.

Other Smart Sensors and Sensor Arrays


Bakeries worldwide rely on the  SCORPION® 2 Digital Humidity Sensor, which measures the moisture content of the thermal environment in both heating and cooling processes. It is appropriate for proofers, ovens, dryers, and cooling tunnels.


Insufficient or excessive temperatures while baking can lead to undesirable changes in taste and texture. The Scorpion® 2 Temperature Sensor Array measures temperature at product level, in fixed positions across the conveyor, and delivers a precise picture of temperatures from side-to-side and end-to-end.

Air Velocity

Oven air flow influences the coloration, texture, firmness, and baking time of your final product, which makes measuring air velocity with the SCORPION® 2 Air Velocity Sensor important. The profiles will help you spot airflow differences between baking zones and unwanted air currents at the entrance or exit of the oven that results in inconsistent baking.
