The Track-It™ Extreme Temperature Data Loggers are battery powered stand alone data loggers that record up to 30,000 samples of temperature data. The units are easily configured using the included Track-It™ Software. Simply plug the logger into the Extreme Logger Reader (required additional item) which connects via a standard USB cable to any open USB port on your PC and the Track-It™ Software automatically identifies the logger. The Logger communicates via the Extreme Logger Reader without opening the logger so long term integrity of the housing is ensured. The Track-It™ Extreme Temperature Logger housing is made of 316L Stainless Steel and meets IP68 rating standards. Set the unit up to start or stop recording immediately, at a predetermined time and date, or only at certain temperature values. The sample storage rate can be set from 1 sample every 2 seconds up to 1 sample every 24 hours. The on board data storage is non-volatile so data will not be lost in the event of a depleted battery.
