DS1922E-F5 thermochrons (high capacity) 0 to +140C (old stock)
All in good working order but date code is Dec 2014.
The DS1922E temperature logger iButtons® are rugged, self-sufficient systems that measure temperature and record the result in a protected memory section. The recording is done at a user-defined rate. A total of 8192 8-bit readings or 4096 16-bit readings taken at equidistant intervals ranging from 1s to 273hrs can be stored. In addition to this, there are 512 bytes of SRAM for storing application-specific information and 64 bytes for calibration data. A mission to collect data can be programmed to begin immediately, or after a user-defined delay or after a temperature alarm. Access to the memory and control functions can be password protected. The DS1922E is configured and communicates with a host computing device through the serial 1-Wire® protocol, which requires only a single data lead and a ground return. Every DS1922E is factory-lasered with a guaranteed unique 64-bit registration number that allows for absolute traceability. Accessories permit the DS1922E to be mounted on almost any object, including containers, pallets, and bags.
