FlexStr8 Announces NFC Temperature Logger for Cold Chain Monitoring

Share Article

Flexstr8 has launched a new product: a smart label that provides a complete temperature history of your perishable goods, that is disposable and thin enough to be easily integrated into packaging.

FlexStr8 Temperature Logging Smart Label

Cold chain logistics play an increasingly important role in transportation of products in the biopharmaceuticals, chemical, and the agricultural industries. To be effective, safe, & profitable, these products need to be monitored throughout the cold chain cycle.

“Current temperature loggers are expensive, bulky, and have poor battery life. Furthermore, most data loggers are built under the assumption that they will be reused”, says Eric Casavant, Head of Product Development for Flexstr8. “However, many customers stated that they rarely get their data loggers back after shipment, prompting us to make an inexpensive disposable logger.”

FlexStr8 has developed a cost effective, long lasting, intelligent, and disposable smart label with an exceptional lifespan (1 year+ depending on the logging rate) and a large memory (28 KB allowing 14000 measurements). This is coupled to an internal accurate temperature sensor (default +/- 0.5C) with a range of -20⁰ C to 50⁰ C. The internal time reference offers accountability and traceability across the entire logistics chain of exposure.

Communication with the tag is done through Near Field Communication (NFC), a quickly growing wireless communication technology that is now available on most mobile devices sold worldwide. "Accurate temperature logging and time stamping allows detailed analysis across the increasingly complex cold chain supply", adds Ralph Roessler, President of FlexStr8, Inc., " This allows corrections to be made and liability assigned.

The free FlexStr8 android app turns the label on or off, allows the log interval to be set (as short as every 5 seconds and as long as every 10 hours), and allows temperature limits to be set. Logged data is graphically displayed and can be dumped to device memory, uploaded to the cloud, and/or emailed for further analysis.
