Introduction
Thankyouforselectingthe‘single‐use’ExtechModelTHD5USBTemperatureDatalogger.This
dataloggerisspecificallydesignedformonitoringthetransportationofproductssubjecttocold
chainrequirements.

TheTHD5isaneasy‐to‐use,waterproof(IP65),andportableUSBTemperatureDatalogger.The
THD5usesaUSB2.0connectorthatcanbepluggedintoaPCforuser‐customizeddatalogger
setup.TheTHD5canthenbeplacedinanareawheretemperatureistobemonitored.Once
placed,theusercanpresstheSTARTbuttontobeginrecording.Whencompleted,theTHD5can
thenbepluggedbackintothePCwhereaPDFreportofloggedtemperaturereadingscanbe
generated(AdobeReader®softwarerequired).

Ten(10)one‐time‐usedataloggersareprovided;eachcanlog8192temperaturereadings.This
deviceisshippedfullytestedandcalibrated.

Pressandholdthe‘STOP’buttonfortwosecondstostopthedatalogger(thelogger
automaticallystopswhenthelogreaches8192readings).Alternatively,plugtheloggerdirectly
intothePCUSBporttostoptheloggingandtogenerateaPDFreport.Afterafewsecondsthe
PDFreportwillbegenerated.ThePDFreportincludesreadingdataandtrendgraph.Thestatus
LEDswillblinkwhiletheloggerisgeneratingthePDFreport.
