The LogTag TRIX -8/TRIX-16 is a versatile, wide range, multi-trip temperature recorder, capable of reading up to 8,000 recordings with temperature levels ranging from -40°C to +85°C (-40°F to +185°F). Enclosed in a robust and durable polycarbonate case, the TRIX-8/TRIX-16 features a real-time clock, providing date and time stamps for each temperature reading.

When the temperature-sensitive products are exposed to unacceptable conditions, the unit can alert users if any temperature breach has happened through a visual indicator on the front.

Users can retrieve and download data by using the LogTag Interface and LogTag Analyzer software. These accessories allow the LogTag TRIX-8/16 to be set-up easily for recording conditions including:

  • delayed start time,
  • sampling interval
  • number of readings
  • continuous or fixed number of readings
  • defined conditions to activate the ‘alert’ red light indicator

These downloaded data also provides facilities for charting, zooming, listing data statistics and allows for exporting the data to other applications such as Excel.

The LogTag TRIX-8/16 data logger complies with the relevant international standards for temperature monitoring devices, including FCC, CE, C-TICK, TÜV, EN12830, WHO PQS and RoHS.



  • Product Model TRIX-8
  • Sensor Measurement Range -40°C to +85°C (-40°F to +185°F).
  • Operating Temperature Range -40°C to +85°C (-40°F to +185°F).
  • Storage Temperature Range -30°C to +55°C (-22°F to +131°F).
  • Rated Temperature Reading Accuracy Better than ±0.5°C for -20°C to +40°C. Better than ±0.7°C for -30°C to -20°C and +40°C to +60°C. Better than ±0.8°C for +60°C to +85°C. Better than ±0.9°C for -40°C to -30°C. Actual performance is typically much better than the rated values. Please see the Rated Absolute Accuracy chart below. Accuracy figures can be improved by recalibration.
  • Rated Temperature Reading Resolution Less than 0.1°C for -40°C to +40°C. Less than 0.2°C for +40°C to +80°C. Less than 0.4°C for +80°C to +85°C. Please see the Rated Native Resolution chart below. LogTag Analyzer® currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag®.
  • Sensor Reaction Time Typically less than 5 minutes (T90) in moving air (1m/s).
  • Recording Capacity 8031 temperature readings. 53 days @ 10min logging, 80 days @ 15min logging.
