We build data loggers for monitoring food products.

MadgeTech has been a key resource for the food and beverage industry for over 20 years, offering a wide range of temperature monitoring solutions. We have a deep commitment to facilitating regulatory compliance and promoting best practice in food safety. MadgeTech data loggers and monitoring systems have become synonymous with HACCP compliance and process verification throughout the food industry, both domestically and internationally.

As a provider of leading-edge technology, MadgeTech offers a diverse line of wireless data logging systems for environmental and facility monitoring. This allows FSQA personnel to see both product and process temperatures in real-time. From refrigerators to freezers and blast chillers, from the production floor to packaging and storage, MadgeTech provides an easily scalable temperature and humidity data monitoring solution for even the most challenging environments. 

Our goal is to continue to provide the tools needed to help food safety professionals perform their jobs more effectively and efficiently.

  • HiTemp140
    The HiTemp140 is made from food-grade stainless steel and come in a variety of both rigid and flexible probes. These rugged loggers can withstand temperatures of up to 284 °F (140 °C) and are completely submersible....

  • The HiTemp140 is a stainless steel, submersible temperature data logger built for use in harsh environments. This data logger can withstand temperatures up to 140 °C (284 °F) and has an accuracy of +/-0.1 °C (0.18 °F).

    The HiTemp140 can store up to 32,700 readings, and features a rigid external probe capable of measuring extended temperatures up to 260 °C (500 °F). Custom probe lengths up to 7 inches are available. The HiTemp140 records date and time stamped readings, and has non-volatile solid state memory. This allows the device to retain recorded data even if the battery becomes discharged.

    The MadgeTech Software makes starting, stopping, and downloading the HiTemp140 simple and easy. Graphical, tabular and summary data is provided for analysis and data can be viewed in °C, °F, K or °R. The data can also be automatically exported to Excel® for further calculations.
  • RFOT
    MadgeTech’s RFOT wireless, continuous monitoring data logging system provides a streamlined solution for measuring and recording internal product temperatures throughout the cooking, smoking, cooling and storage of meat and food products....

  • MadgeTech’s RFOT is the most advanced wireless temperature data logger in the meat industry today. It's perfectly suited for smokehouses, ovens and other cooking processes up to 100 °C (212 °F), as well as refrigerators and freezers down to -20 °C (-4 °F). The RFOT is completely splash-proof and is available with the following rigid piercing probe types:

    • RFOT-FR: Fast response 1.75 inch (45 mm) probe (for smaller meat products)
    • RFOT-4-TD: 4.0 inch (102 mm) transitional diameter probe (for smaller meat products)
    • RFOT-4: 4.0 inch (102 mm)  probe
    • RFOT-7: 7.0 inch (177 mm)  probe

    This state-of-the-art device records and transmits internal product temperature readings back to a central computer for instant real-time monitoring. In addition to wirelessly transmitting data, the RFOT also stores each reading to internal memory for backup which can be retrieved wirelessly at a later time.

    MadgeTech’ software features user-programmable critical control points, called “cooling flags” to assist in compliance with USDA Appendix B. Users can also configure email and text message notifications in the event a logger receives data outside of the desired range.

  • RFRHTemp2000A
    The MadgeTech RFRHTemp2000A wireless data logger is designed to monitor temperature & humidity in warehouses, coolers, freezers and other sensitive environments. Data can be viewed on LCD screen or remotely using the MadgeTech Software or MadgeTech Cloud....

  • The RFRHTemp2000A is two-way, wireless temperature and humidity data logger with LCD. Designed with external humidity and RTD-based temperature sensors, the device provides a fast response time for both parameters.

    For customer convenience, functions include starting, stopping and downloading from the device wirelessly using the RFC1000 wireless transceiver. This allows customers to quickly access data in real-time or back to a central PC.

    The digital display provides the current reading for both the humidity and temperature channels with minimum, maximum and average statistics accessible for a quick snapshot of the logged data. The RFRHTemp2000A features user-programmable alarm settings for both temperature and humidity parameters.

    The RFRHTemp2000A can be used as a single, wireless data logging system, or it can be expanded to a large-scale system. The RFRHTemp2000A utilizes the MadgeTech Software where data can be viewed in graphical or tabular formats and summary and statistics views are available for further analysis. The software features export to Excel®, data annotation, digital calibration and more.
