Evidencia Thermassure RFID tags have some unique features not offered by conventional temperature loggers.
The Evidencia Thermassure RFID tags store a 96 bit ePC code for logistics, and high accuracy temperatures with a standard, but expandable, 4000 reading capacity and accuracy of better than 0.3C.
The Evidencia Thermassure RFID tags are passive RFID devices and so are approved by FAA for use in aircraft and FDA for food and pharmaceutical applications.
Data can be downloaded any number of times, during a mission, and details of the date and time and reader serial number are stored. Furthermore, the data can be read with short download times, through packaging, and even gel cooling packs, using remote RF readers of USB PC readers.
Temperature ranges from –40 to 70C or –80 to 150C with external probes can be measured – and all versions are fully immersible to IP67.
The Evidencia Thermassure RFID tags have LEDs to indicate function and alarm status. Tag types include single use and multiuse versions as well as loggers and trackers.
Loggers store temperatures and other data, with day date and time, so the output can be a time temperature graph.
Trackers store only the number of minutes spent within defined temperature ranges, and so generate a temperature histogram. This provides all the data needed to assess product quality, for example – exactly how many minutes spent and what temperatures in an out of specification situation.
Safety or available shelf life can then be reliably assessed.
The Evidencia Thermassure RFID tags are compact, light, and can be mounted inside a carton to maintain its tamper proof status, while data can be downloaded with a reader.
If visible feedback of alarm status, or deep core temperatures are required, the external probe tags can be slipped into a document holder stuck to a carton, and the sensor embedded in the contents. The cartons can still be stacked – the loggers are so thin and rugged.
Evidencia Thermassure RFID tags are available from ECEFast.
