The LT5GEO External Probe Cellular Logger is a specialized temperature data logger that uses an external probe combined with cellular data transmission capabilities, enabling real-time monitoring of environmental conditions in the supply chain. The device is designed to measure temperature in environments where integrated sensors cannot be placed directly, such as deep freezers, cold storage, insulated containers, or processes requiring high accuracy. The LT5GEO uses LTE Cat M1/EGPRS connectivity to automatically send data to the LogTag® Online platform, allowing users to remotely monitor and receive immediate alerts when temperatures exceed preset thresholds.
