The TempTale®RF (TTRF) temperature monitor is part of Sensitech's family of precision devices designed to track and collect time and temperature data about temperature-sensitive shipments. These highly reliable, wireless monitors collect and store temperatures for a wide array of in-transit and storage applications. TTRF is designed with configurable time and temperature limits to trigger time-out-of-range alerts, along with an easy-to-read LCD screen for immediate shipment evaluation.

Use our RF monitor to:

  • Measure and store ambient temperature data at set intervals
  • Set alarm limits
  • Read information via LCD display
  • Start or stop data collection using the front panel buttons
  • Store and record location information when other ColdStream® RF Infrastructure components are detected
  • Operate within the 915 MHz or 868 MHz ISM band for efficient transmission in high water content product situations
  • Leverage reader-talk-first mode -- monitors will not transmit until they are in the vicinity of an active ColdStream Infrastructure component (i.e., an operational TTRF Gateway and/or TTRF Repeater); this functionality is required for air transit
