Logtag TRED30 and UTRED30 Digital Data Loggers

The LogTag® Logtag TRED30 and UTRED30 Digital Data Loggers provide reliable, continuous temperature monitoring for vaccines stored in refrigerators and freezers. Designed for CDC/VFC-compliant temperature monitoring applications, the UTRED30-WiFi SP automatically uploads real-time temperature data to your LogTag® Online cloud account through an existing WiFi network and supports ISO/IEC 17025 NIST-traceable calibration.

With an external sensor measurement range of -40°C to +99°C (-40°F to +210°F), the UTRED30-WiFi SP provides accurate temperature monitoring through an external buffer bottle probe. The logger stores up to 16,129 temperature readings and maintains up to 30 days of minimum, maximum, alarm duration, and alarm trigger statistics for convenient review directly from the display.

Temperature excursions are indicated through audible and flashing LED alarms, while minimum and maximum temperature readings can be checked and reset at any time. When WiFi is unavailable, recorded data can also be downloaded through LogTag Analyzer software or accessed as a PDF without additional software.
