Product Details

Digital thermometer measures temperature 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
Water resistant or waterproof if placed inside DS9107 iButton capsule
Automatically wakes up and measures temperature at user-programmable intervals from 1 to 255 minutes
Logs consecutive temperature measurements in 2KB of datalog 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 battery-backed SRAM
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 registration number (8-bit family code + 48-bit serial number + 8-bit CRC tester) assures absolute 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
