LogTag Humidity Logger

The Best Transit Humidity Monitor

LogTag Humidity LoggerThe LogTag Humidity & Temperature Recorder measures and stores up to 8000 sets of high resolution humidity and temperature readings over 0 to 100% RH & -40°C to +85°C (-40°F to +185°F) measurement ranges.

You can trust the LogTag Humidity Logger in almost any rugged environment.  It has all of the superior features of the LogTag line, and brings state-of-the art humidity sensing to you in an affordable and compact package.

Using the LogTag Interface and LogTag Analyzer Software, you can control all aspects of performance, including delayed start, sampling interval, number of readings, 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, listing data statistics and allows exporting the data to other applications such as MS Excel.
