Redefining Cold Chain Monitoring

Fragmented temperature monitoring. Data aggregation challenges. Incomplete tracking of shipments at the “first mile” and “last mile.” These are serious problems in the cold chain that result in the disqualification of millions of doses of biologic drugs annually.

Enter the CubiSens™ XT1, a small, wireless family of smart sensors and a revolutionary solution for monitoring temperature and tracing products, such as food and doses of biologics, at the item level. The XT1 can be attached to both large shipments and individual items to provide the temperature history for a product’s lifetime.

Enabling Item-Level Tracking

Use the XT1 to prove originality of product and take action to prevent the disqualification of shipments. The XT1 is small enough to be affixed to individual boxes, vials, and syringes, and can operate in sensing mode for up to 3 years. Pharmaceutical manufacturers, wholesalers, and “3PLs” now have complete visibility of temperature history throughout the supply chain.

Smart, Fine-Grain Sensing, Superior Results

The XT1 is a comprehensive tracking solution that is both easy to use and deploy. Use the XT1 as a digital record of proof of regulatory compliance. With the XT1, users can mitigate the threat of lost revenue.


Wirelessly track the temperature of individual and high-value, high-risk, products, such as biologics, for a product’s lifetime.


Monitor biopharmaceuticals from the “first mile” to the “last mile” of the cold chain to ensure quality and compliance.
