The MadgeTech RFOT wireless meat temperature data logger with 2-way communication can be used in smoke houses, ovens and other cooking processes up to 212°F as well as refrigerators and freezers down to -4°F. It records and transmits internal product temperature readings back to a central computer for instant real-time monitoring.
