The HAXO-8 is a humidity and temperature data logger 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%. The 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 stamps. Users can also access and download the data by using the LogTag Interface and LogTag Analyser software. Accessories can also be used to enable the easy set-up of the LogTag. The LogTag Analyser also features zooming, charting, listing data facilities, and exporting data to other applications such as Excel. The HAXO-8 Data Logger meets all international requirements and standards for temperature monitoring devices such as RoHS, FCC, CE, C-TICK.
