Available in packs of 10, the ultra low cost single-use EL-CC-2-001 PK10 Chilled Goods data logger measures and stores both temperature and humidity information. The unit comes pre-configured with High 8°C and Low 2°C Alarms - simply press the button to start logging. During a logging session, pressing the button will light up the status LEDs to give a quick indication of whether the temperature has exceeded an alarm condition at any point. Once your session is completed, tear open the IP67-rated plastic wallet to reveal the USB connector and plug it in to your PC. Use the free EasyLog CC software for Windows to download and graph the data.
