The LogTag® TREX-8 is a versatile, wide range, multitripTemperature Recorder with interchangeable External Probes,featuring high resolution temperature readings over ameasurementrangeof-40°Cto+99°C(-40°Fto+210°F).

InterchangeableRemoteProbes–LogTagremotetemperatureprobes are interchangeable provided they are changed withLogTagST100typeremotetemperaturesensors.

Using the LogTag® Interface and LogTag’s freely availablecompanion software LogTag® Analyzer, the LogTag is easilyset-upforrecordingconditionsincludingdelayedstart,samplinginterval, number of readings, continuous or fixed number ofreadingsandconfigurationofconditionstoactivatetheALERTindicator.

Readings are downloaded using LogTag® Analyzer whichprovidesfacilitiesforcharting,zooming,listingdatastatisticsandallowsexportingthedatatootherapplicationssuchasExcel.

The LogTag® TREX-8 complieswith the relevant internationalstandardsfortemperaturemonitoringdevices:FCC,CE,C-TICKandRoHS.Thisdemonstratesthequalityandsuitabilityof theLogTag®TREX-8fortemperaturemonitoringapplicationswhereaccuracyandconsistencyisrequired.
