Software-Less PDF Generation 
Temperature / Alarm Data Plus Graphs

Fridge-tag® 2L is the ideal Temperature Data Logger for the continuous monitoring of sensitive Vaccines and Pharmaceuticals stored in medical refrigerators & freezers. No software needed to generate temperature & alarm data. As soon as the Fridge-Tag® 2L is connected via USB to a PC or Mac it creates a PDF and an ASCII file. The PDF file provides a daily summary of temperature activity (selectable: 28, 56, 84 or 112 day overview) PLUS 8 weekly graphs of temperature performance. Temperature readings are recorded every 5 minutes and can be found in a table within the TXT file. Thanks to the electronic signature the raw data can be verified as compliant with FDA regulations 21 CFR Part 11. This means that each month you obtain a report and the assurance that your temperature-sensitive goods are stored in accordance with regulations. The data logger’s external thermometer probe is sealed in a Bio-Safe glycol filled bottle to buffer temperature variations. Meets and exceeds the latest VFC CDC requirements published in the Guidelines for Storage and Temperature Monitoring of Refrigerated Vaccines

Exact measurement of temperature and time The Fridge-tag® 2L is a high-precision, electronic temperature monitor. It is 100% calibrated and has a measurement precision of +/- 0.5 °C. Temperature measurement occurs every minute throughout the entire monitoring time. This guarantees faultless and extremely accurate measurement results. Even if an alarm limit has been exceeded and the Fridge-tag® 2L alarm is displayed, it accumulates each additional temperature threshold violation. The precision time measurement is generated by a built-in quartz. NIST/ILAC traceable.

Data read-out without software via USB As soon as the Fridge-tag® 2L is connected via USB to a PC or Mac, it creates a PDF or an ASCII file. Thanks to the electronic signature the raw data can be verified to be in compliance with the FDA 21 CFR Part 11 regulations. Any changes are immediately recognized and the document rejected. This means that each month you obtain a report and the assurance that your temperature-sensitive goods are stored and recorded in accordance with regulations.
