LogTag HASO-8

Single-use Humidity & Temperature Logger

Single-use Humidity & Temperature Logger


  • Record high resolutionTemperature & Humidity readings simultaneously
  • Push-to-start button with optional delay or a specific time & date
  • Comprehensive customization options including alert settings, sample interval and trip duration.
  • Up to 8,000 paired humidity and temperature recordings
  • In-transit inspections can be recorded at the push of a button.

The LogTag® HASO-8 is a single-use Humidity & Temperature Recorder that measures and stores up to 8000 sets of high resolution humidity and temperature readings over a measurement range of 0 to 100 % RH & -40 °C to +85 °C.

Enclosed in a robust and durable polycarbonate case - the HASO-8 is equipped with a unique humidity & temperature sensor arrangement providing fast reaction time to humidity & temperature change and a real time clock which 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, HASO-8 Single-Use Humidity & Temperature Logger sampling interval, 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.
The LogTag® HASO-8 complies with the relevant international standards for humidity & 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 humidity & temperature monitoring applications where accuracy and consistency is required.

Please note: An interface is required for configuration and reporting
