LogTag® HAXO-8 Multi-Use Humidity & Temperature Logger

LogTag® HAXO-8 Multi-Use Humidity & Temperature Logger


All applications where capturing both temperature and humidity data is important

Product Summary

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 Highlights

  • Alert indicator – indicates if readings are outside of preset limits
  • OK indicator indicates if still recording and if readings within configured limits
  • Inspection mark in log by push button
  • Push Button Logging start
  • Rapid Download! Takes only seconds to download recordings
  • 'Pre-Start' logging - Logtag® can be configured to record even if it has not been started.
  • High performance at low cost
  • Credit card sized case – thin enough to be easily mailed “letter rate”.
  • Real time clock records time & temperature simultaneously
  • Easy to use LogTag®Analyzer software that runs on any PC configures LogTag® for recording then downloads resulting data for analysis. Data can also be exported to formats compatible with other applications such as Excel
  • Fine resolution of measurement – 0.1% RH & 0.1 °C
  • Re-calibration to achieve higher accuracy possible
  • Replaceable sensor air filter

*Optimal Storage Condition For optimal Humidity logger storage, store units in original packaging in an air conditioned area. Storage temperature shall be in the 
range of 10°C to 50°C and humidity at 20 %RH to 60 %RH. Ensure good ventilation (fresh air supply) in storage area to avoid high 
concentrations of volatile chemicals. Do not store units in the same room as solvents or any other strong smelling products.
