The Fridge-tag® 2 E is a USB-enabled electronic temperature monitoring and data logger equipped with an external sensor for accurate temperature measurement inside refrigerators, freezers, cold storage, or hard-to-reach environments. The device allows for continuous monitoring, visual display on an LCD screen, and PDF/ASCII report generation for quality control purposes.
The Fridge-tag® 2 E operates independently, requiring no software, and its data is digitally signed to prevent tampering. It meets GSP, GDP, WHO, and FDA requirements for the storage of vaccines, pharmaceuticals, and medical biological products.
