The LogTag® TREX-8 is a versatile, wide range, multitrip Temperature Logger with interchangeable External Probes, featuring high resolution temperature readings over a measurement range of -40°C to +99°C (-40°F to +210°F).
Interchangeable Remote Probes – LogTag remote temperature probes are interchangeable provided they are changed with LogTag ST100 type remote temperature sensors.
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, 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 Excel.
The LogTag® TREX-8 complies with the relevant international standards for temperature monitoring devices:- FCC, CE, C-TICK and RoHS. This demonstrates the quality and suitability of the LogTag® TRIX-8 for temperature monitoring applications where accuracy and consistency is required.

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 (0.2°F) for measurements -40°C to +40°C (-40°F to +104°F).|
Less than 0.2°C (0.4°F) for measurements +40°C to +80°C (+104°F to +176°F).
Less than 0.6°C (0.5°F) for measurements +80°C to +99°C (+176°F to +210°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®.
