The TandD RTR-601 Food Core Temperature Data Logger

The TandD RTR-601 Food Core Temperature Data Logger is a wireless food core temperature data logger that is effective for HACCP-compliant temperature management for food safety. The water and oil proof design (IP68 rating) makes it ideal for use in food-processing environments. With the push of a button, the device records temperature, measurement time, user, item, and upper/lower limit judgment result.

Recorded data in the RTR-601 can be periodically collected by the Base Unit (RTR-500NW/500AW) via wireless communication, and automatically sent to a designated e-mail address or an FTP server. This makes it perfect for seamless temperature management.

There are four models depending on the sensor type:





  • RTR-601-110: Short Sensor
  • RTR-601-130: Long Sensor
  • RTR-601-E10: Cable Type Short Sensor
  • RTR-601-E30: Cable Type Long Sensor

Note: The RTR-601 requires a battery charger dock.


  • *1: A Battery Charge Dock (RTR-6BD) needs to be purchased separately.
  • *2: Customers wishing to use the RTR-500 as a Base Unit, please contact your local distributor for the communications protocol specifications to write your own software.
