LogTag HAXO-8

Multi-use Humidity & Temperature Logger

Multi-use Humidity & Temperature Logger


  • Alert indicator – indicates if readings are outside of preset limits
  • OK indicator indicates if still recording and if readings within configured limits
  • Record high resolution Temperature and Humidity readings simultaneously.
  • Up to 8,000 paired humidity and temperature recordings
  • Real time clock records time & temperature simultaneously
  • Re-calibration to achieve higher accuracy possible
  • For multiple applications use



The LogTag® Humidity & Temperature Recorder measures and stores up to 8000 sets of high resolution humidity and temperature readings over 0 to 100%RH & -40 °C to +85 °C measurement ranges.

Using the LogTag® Interface and LogTag’s freely available companion software LogTag® Analyzer, the LogTag® is easily set-up for recording conditions including delayed start, sampling interval, number of readings, continuous or fixed number of readings and configuration of conditions to activate the ALERT indicator. Readings are downloaded using LogTag® Analyzer which provides facilities for charting, zooming, listing data statistics and allows exporting the data to other applications such as Excel.

Please note: An interface is required for configuration and reporting


Product Model HAXO-8
Temperature Sensor Measurement range -40 °C to +85 °C (-40 °F to +185 °F)
Recorder operating temperature range -40 °C to +85 °C (-40 °F to +185 °F)
Storage Temperature Range +10 °C to +50 °C (50 °F to +122 °F)*
Rated Temperature reading accuracy Better than ±0.45 °C (±0.8 °F) for +0 °C to +50 °C (+32 °F to +122 °F), typically ±0.3 °C (0.6 °F). Better than ±0.8 °C (±1.4 °F) for +50 °C to +80 °C (+122 °F to +176 °F), typically ±0.5 °C (0.9 °F). Better than ±0.95 °C (±1.7 °F) for -40 °C to +0 °C (-40 °F to +32 °F), typically ±0.6 °C (1.1 °F). Actual performance is typically much better than the rated values. Accuracy figures can be improved by recalibration
