HASO-8 single-use Humidity and Temperature Logger measures and stores up to 8000 sets of high-resolution humidity and temperature readings over a measurement range of 0 to 100%RH and -40°C to +85°C (-40°F to +185°F).

Enclosed in a robust and durable polycarbonate case – the HASO-8 is equipped with a unique temperature sensor arrangement providing a fast reaction time to temperature change and a real-time clock that provides date/time stamps for each temperature reading.

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, a 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, and listing data statistics and allows exporting the data to other applications such as Excel.

HASO-8 complies with the relevant international standards for temperature monitoring devices:- FDA 21 CFR Part 11, EC Annex 11, IATA’s 2018 Dangerous Goods Regulations 59th Edition, FCC, CE, RCM, and RoHS. This demonstrates the quality and suitability of the LogTag® HASO-8 for temperature monitoring applications where accuracy and consistency are required.
