Product Description

TREX-8-Multi-Use with External Probe

The LogTag® TREX-8 is a versatile, wide range, multi-trip Temperature Recorder 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 Cradle and the freely available companion software LogTag® Analyzer, the LogTag® TREX-8 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.
