LIBERO GF ext

The LIBERO GF ext from Elpro is a real-time data logger for precise cold chain monitoring during transport. It is suitable for various applications and facilitates the shipping of temperature-sensitive products. The internal sensor is highly accurate and fully calibrated. Additionally, an external Pt100 sensor (with M8 connector) can be connected to monitor a further temperature range of -200 °C to +400 °C, making it ideal for ultra-freezing devices and cryogenic containers.

The data logger is reusable, reconfigurable, and has a battery life of over one year. In addition to temperature, it also monitors light, motion, tilt, and the location of the goods. All measurements are automatically stored in a secure cloud. The automatic flight detection allows for use in air freight. An integrated display provides a clear overview of the data and up to 31,000 temperature values can be temporarily stored. After transport, the status can be read directly and reports can be downloaded from the cloud.
