The LogTag with built-in USB connection works in exactly the same way as other LogTags except for one important difference – it does not need a separate USB Reader. The LogTag plugs directly into the USB port of your Windows computer.
So, if you only need one or two loggers, or you have multiple sites with only one logger, this is an economical choice.
The USB LogTag has another party trick – when you plug it into a computer it mounts like a USB drive. The drive contains one file: the data report as a PDF.
The automatically generated PDF make this an ideal logger for tracking your cold chain transport. Pack a USB LogTag with your goods and the receiver can plug it into any Windows PC (no software needed) and download the report.

Actual performance is typically much better than the rated values. Please see the Rated Absolute Accuracy chart below.
Accuracy figures can be improved by recalibration.
|Rated Temperature Reading Resolution||Less than 0.1°C/F.|
Please see the Rated Native Resolution chart below.
LogTag Analyzer® currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag®.
