The LogTag HAXO-8 is a humidity and temperature logger, capable of measuring and storing up to 8000 sets of humidity and temperature readings. It can record measurements ranging from 0 to 100% RH and -40°C to +85°C (-40°F to +185°F). 

Enclosed in a robust and durable polycarbonate case, the external temperature sensor on the HAXO-8 humidity and temperature recorder provides fast reaction time to temperature change and a real-time clock which provides accurate date and time stamps for each temperature reading. 

Users can retrieve and download data through the LogTag Interface and LogTag Analyzer software. These accessories allow the LogTag HAXO-8 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

The LogTag Analyzer software provides facilities for charting, zooming, listing data facilities and allows exporting the data to other application such as Excel. 

The HAXO-8 data logger complies with the relevant international standards for temperature monitoring devices, including FCC, CE, C-TICK, and RoHS.
