The DS1925L 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 122K 8-bit readings or 61K 16-bit readings taken at equidistant intervals ranging from 5min to 273hrs can be stored.
In addition, there are 512 bytes of nonvolatile memory for storing 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 DS1925L 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 DS1925L 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 DS1925L to be mounted on almost any object, including containers, pallets, and bags.

  • Programmable Recording Start Delay After Elapsed Time or Upon a Temperature Alarm Trip Point
  • Two-Level Password Protection of All Memory and Configuration Registers
  • Measure and Report Internal Battery Level and Output-Logged Data if a Battery is Depleted
  • Durable Stainless-Steel Enclosure Withstands Harsh Environments and Conditions
  • Communicates to a Host System with the Single-Contact 1-Wire Interface
  • -40°C to +85°C Operating Temperature Range

The DS1925L is an ideal device to monitor for extended time periods the temperature of any object it is attached to or shipped with, such as fresh produce, medical drugs, and supplies, and for use in refrigerators and freezers.

Note that the initial sealing level of the DS1925L achieves IP56.
Aging and use conditions can degrade the integrity of the seal over time, so for applications with significant exposure to liquids, sprays, or other similar environments, it is recommended to place the DS1925L in the DS9107 iButton capsule.

For protection against surface moisture, various chemicals or continuous immersion, refer to the MF1925L iButton Temperature Logger, water resistant according to IPX8.
