  • Interchangeable External Probe with high quality gold plated connector
  • Display shows current time & temperature plus alarm status
  • 30 day statistics summary reviewable on device display
  • Fixed Battery (can't be replaced).  Typical life is 2 to 3 years.
  • IMPORTANT: Each location (not each logger) requires a LogTag Cradle in order to program and retrieve data from the logger.
  • The LogTag® TRED30-7F Temperature Recorder uses an External Probe (NOT INCLUDED) to measure and store up to 7770 temperature readings over a measurement range of -40°C to +99°C (-40°F to +210°F).


  • Statistical temperature and alarm duration readings for up to 30 days can be reviewed on the display.  
  • The display of current temperature and previous alarms is an important feature in “static” Applications such as cool rooms and refrigerators.
  • For Vaccine Storage, you may want to use the ST100J-30 Probe with the Glycol Buffer Kit and the Wall Mount.

The display elements on this LogTag data logger are arranged so they to show ‘at a glance’ if temperature violations have occurred between now and 29 days ago. The display also shows the current temperature reading, the current time, battery status and if the digital data logger is currently recording.
