The LT5GEO-LE cellular data logger was developed for vaccines and biological samples that require storage at ultra-low temperatures or transport on dry ice. It provides continuous visibility, precise measurement data, and alerts down to -90 °C.
As soon as an alarm is triggered, you receive real-time notifications and can keep critical environmental conditions under constant surveillance.
All data is automatically uploaded to the LogTag Online Cloud—for global live access, reports, and alerts.
Thanks to modern cellular technology with 4G/5G connectivity and 2G fallback, the LT5GEO reliably transmits measurement and location data to the LogTag Online Cloud. Your team can view the data from anywhere, generate reports, and respond quickly to deviations.
The external sensor measures temperatures down to -90 °C. Additionally, light and shock sensors provide insights into how your goods were handled during transport or storage. This gives you a comprehensive overview of the condition, location, and potential stresses on your shipment.
Unbeatable Range of Features
The LT5GEO is a powerful addition to the LogTag data logger series. In addition to temperature measurement, it offers GPS tracking, light detection, and shock detection.
Instant notifications for parameter deviations
GPS tracking via LogTag Online
Flight mode is automatically detected and activated via LogTag Online
Shipment status detection using location, shock, light, and temperature sensors
Automatic upload of data to the LogTag Online Cloud
Start and stop functions controlled via a single button
Up to 1 million measurement values available at any time via LogTag Online, including report generation
Complies with FCC, CE,
DO-160H, and FDA 21 CFR Part 11
Data is automatically uploaded to the LogTag Online Cloud via a cellular connection. This allows you to check the location and status of your package at any time. Available for viewing on your PC or on your mobile phone using the LogTag Mobile App.
