The HAXO-8 is a humidity and temperature data logger that is designed to record and store up to 8,000 sets of temperature and humidity readings. It is capable of recording temperature readings between -40°C to +85°C (-40°F to +185°F) and relative humidity between 0 to 100%. HAXO-8 is enclosed in a robust and durable polycarbonate case; the external temperature sensor of the HAXO-8 can provide fast and precise data readings along with a real-time clock for accurate data and time stamp.
Users can also access and download the data by using the LogTag Interface and LogTag Analyzer software. Accessories can also be used to enable the easy set-up of the LogTag.

The LogTag Analyzer also features facilities for zooming, charting, listing data facilities and exporting of data to other applications such as Excel. The HAXO-8 data logger meets all international requirements and standard for temperature monitoring devices such as RoHS, FCC, CE, C-TICK.

LogTag accessories include:

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