SPECIAL FEATURES

Digital thermometer measures temperature in

1/8°C increments with ±1°C accuracy

Built-in real-time clock (RTC) and timer has

accuracy of

±2 minutes per month from 0°C

to 45°C

Automatically wakes up and measures

temperature at user-programmable intervals

from 1 to 255 minutes

Logs up to 2048 consecutive temperature

measurements in protected nonvolatile (NV)

random access memory

Records a long-term temperature histogram

with 1/2°C resolution

Programmable temperature-high and

temperature-low alarm trip points

Records up to 24 time stamps and durations

when temperature leaves the range specified

by the trip points

512 bytes of general-purpose read/write NV

random access memory

Communicates to host with a single digital

signal at 15.4kbits or 125kbits per second

using 1-Wire

® protocol

Fixed range: H: +15

°C to +46°C;

Z: -5

°C to +26°C

COMMON iButton FEATURES

Digital identification and information by

momentary contact

Unique, factory-lasered and tested 64-bit reg-

istration number (8-bit family code + 48-bit

serial number + 8-bit CRC tester) assures ab-

solute traceability because no two parts are

alike

Multidrop controller for 1-Wire net

Chip-based data carrier compactly stores

information

Data can be accessed while affixed to object

Button shape is self-aligning with cup-shaped

probes

Durable stainless steel case engraved with

registration number withstands harsh

environments

Easily affixed with self-stick adhesive

backing, latched by its flange, or locked with

a ring pressed onto its rim

Presence detector acknowledges when reader

first applies voltage

Meets UL#913 (4th Edit.). Intrinsically Safe

Apparatus: approved under Entity Concept

for use in Class I, Division 1, Group A, B, C,

and D Locations (application pending)
