iButton High-Capacity Temperature Logger

with 122KB Data-Log Memory

General Description

Beneﬁts and Features

● Provides High-Quality Temperature Exposure

The iButton temperature logger (DS1925) 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 col-

lect 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 DS1925 is configured and communicates

• Temperature Measurement Accuracy of ±0.5°C

with Storage for Up to 125,440 Timestamped

Values

• Flexibility to Monitor and Data-Log Long Duration

Exposures with Short-Duration Time Intervals

• Unique Factory-Lasered 64-Bit Serial Number En-

sures Absolute Traceability Because No Two Parts

Are Alike

• Programmable Sample Rates from 5min to 273hrs

• Programmable Recording Start Delay After Elapsed

Time or Upon a Temperature Alarm Trip Point

• Two-Level Password Protection of All Memory and

protocol, which requires only a single data lead and a

ground return. Every DS1925 is factory-lasered with a

guaranteed unique 64-bit registration number that allows

for absolute traceability. The durable stainless-steel pack-

age is highly resistant to environmental hazards such as

dirt, moisture, and shock. Accessories permit the DS1925

to be mounted on almost any object, including containers,

pallets, and bags.

• Measure and Report Internal Battery Level and

Output-Logged Data if a Battery is Depleted
