DS1922L/DS1922T iButton Temperature Loggers with 8KB Datalog Memory The temperature loggers DS1922L/DS1922T 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 273hr, can be stored. Additionally, 512 bytes of SRAM store applicationspecific information and 64 bytes store calibration data. A mission to collect data can be programmed to begin immediately, after a user-defined delay, or after a temperature alarm. Access to the memory and control functions can be password protected. The DS1922L/DS1922T are configured and communicate with a host-computing device through the serial protocol, which requires only a single data lead and a ground return. Each DS1922L/DS1922T is factory lasered with a guaranteed unique 64-bit registration number that allows for absolute traceability. The durable stainless-steel package is highly resistant to environmental hazards such as dirt, moisture, and shock. Accessories permit the DS1922L/DS1922T to be mounted on almost any object, including containers, pallets, and bags.
