IButton DS1922E Thermochron Data Logger (+15 To +140'C)

Description

The DS1922E iButton® temperature logger is a rugged, self-sufficient system that measures temperature and records the result in a protected memory section. A total of 8192 8-bit readings or 4096 16-bit readings can be stored at recording intervals ranging from 1s to 273hrs. 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. The durable stainless-steel package is highly resistant to environmental hazards such as dirt, moisture, and shock. Accessories permit the DS1922E to be mounted on almost any object, including containers, pallets, and bags.

NOTE: Requires Software and adapter cable to communicate.
