In the world of food processing, safety and consistency are everything—especially when it comes to canned goods. Heat penetration testing plays a critical role in ensuring that each product receives sufficient thermal exposure to eliminate harmful pathogens like Clostridium botulinum. For processors, confidence comes from knowing that every batch meets strict regulatory requirements without overprocessing. That’s where MadgeTech’s precision data loggers come in.

Understanding Heat Penetration Testing

Heat penetration testing involves measuring the internal temperature of a product as it moves through the thermal process, such as retort sterilization. The goal is to ensure that the coldest spot in the container reaches the target temperature for the appropriate amount of time. This data is then used to validate the process and establish critical control points for HACCP programs and FDA compliance.

Precision Tools for Reliable Results

MadgeTech offers a range of data loggers engineered specifically for this task. The HiTemp140-CF, paired with the ThermaLock canning fitting, provides a secure, direct measurement of internal can temperatures during processing. Built to withstand the high-pressure, high-temperature conditions of retort environments, the HiTemp140-CF delivers accurate, time-stamped data ideal for process validation.

For applications where space is limited or smaller containers are used, the NanoTemp125-CF offers the same durability and precision in a compact body that’s about half the size of the HiTemp140. This miniature logger is perfect for tight spaces, yet still delivers the performance needed for rigorous thermal studies.

Streamlined Solutions with the HPT System

MadgeTech also offers the HPT System, a complete kit that includes everything needed for heat penetration testing—data loggers, canning fittings, and software—making it easy to start testing with confidence and accuracy.
