The A927Z RFID Temperature Data Logger by CAEN RFID is a low cost, semi-passive UHF logger tag that allows users to monitor temperature sensitive products like perishable foods and pharmaceuticals, during transportation and storage. The combination of a high resolution sensor, large memory size and standard RFID interface makes it an effective way track and trace products.

The temperature RFID tag can be configured to store samples in intervals from 8 seconds to 18 hours in the internal memory that can contain up to 8,000 samples. The user can define alarms for high and low temperature thresholds.

The A927Z RFID logger can be used for multiple shipments thanks to the long battery life and the reset function.

An external probe model (A927ZET) is also available for purchase. This model makes it possible to measure temperature even inside a shielded box where the RFID field cannot get through, while still giving you the reading from the A927Z.
