The DS192X temperature logger iButton is a rugged, self-sufficient system that measures temperature and records 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, 576 bytes of SRAM store application-specific information. 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 DS1922E is configured and communicates with a host-computing device through the serial 1-Wirę̉ 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. The durable stainless-steel package is highly resistant to environmental hazards such as dirt, moisture, and shock.
While all iButton data loggers are calibrated/validated against NIST traceable reference devices, Maxim offers a web application to generate validation certificates for the DS1922L/T data loggers. Input is an iButton registration number (or list of numbers) and the output is a validation certificate in PDF format. The DS1923 temperature/humidity logger iButton̨̉ is a rugged, self-sufficient system that measures temperature and/or humidity and records 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 DS1923 is configured and communicates with a host-computing device through the serial 1-Wirę̉ protocol, which requires only a single data lead and a ground return. Every DS1923 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 DS1923 to be mounted on almost any object, including containers, pallets and bags.
