Ultra-Low Temp Dry Ice Data Logger W/External Probe
The LTTREL8 Low Temperature Remote Probe Logger measures and stores up to 8000 temperature readings over -80°C to +40°C (-112°F to +104°F) measurement range from associated interchangeable LogTag® ST10 type remote probe temperature sensor (available in lengths up to 3 meters (9’10”).
It is intended for use in monitoring of articles stored at low temperatures such as in dry ice type environments.
LTTREL8 is easily configured for recording conditions including delayed start, sampling interval, number of readings and configuration of conditions to activate the ALERT indicator.

Specifications
SPECIFICATIONS:
Product Model |
LTTREL8 |
External Temperature Sensor Measurement Range |
-80°C to +40°C (-112°F to +104°F). |
Operating Temperature Range |
-20°C to +40°C (-4°F to +104°F). |
Storage Temperature Range |
-10°C to +55°C (14°F to +131°F). |
Rated TemperatureReading Accuracy |
Better than ±1°C (±1.8°F) for -30°C to +20°C (-22°F to +68°F). Better than ±1.2°C (±2.1°F) for -45°C to -30°C (-49°F to -22°F) and +20°C to +40°C (+68°F to +104°F). Better than ±1.7°C (±3.1°F) for -80°C to -45°C (-112°F to -49°F). Actual performance is typically much better than the rated values. Accuracy figures can be improved by recalibration. |
Rated TemperatureReading Resolution |
Less than 0.1°C (0.2°F) for -80°C to 0.0°C (-112°F to +32°F), Less than 0.2°C (0.4°F) for 0.0°C to +20°C (+32°F to +68°F), Less than 0.5°C (0.9°F) for +20°C to +40°C (+68°F to +104°F) LogTag Analyzer® currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag®. |
Sensor Reaction Time |
Typically less than 2 minutes(T90) in moving air (1m/s) for ST10S type |
Recording Capacity |
8,031 temperature readings. 53 days @ 10min logging, 80 days @ 15min logging. |
Sampling Interval |
Configurable from 30 seconds to several hours |
Logging Start Options |
Push button start with optional start delay or specific date & time. |
Recording Indication |
Flashing ‘OK’ indicator / flashing ‘ALERT’ indicator. |
Download Time |
Typically less than 5 seconds for full memory (8031 readings), depending on computer or readout device used. |
Environmental |
IP61. |
Power Source |
CR2450 3V LiMnO2 Battery (Fixed). |
Battery Life |
1 year storage, followed by 2 – 3 years of normal use (based on 15 minute logging, download data monthly). |
Real Time Clock |
Built-in real time clock. Rated accuracy ±25ppm @ 25°C (equivalent to 2.5 seconds/day). Rated temperature coefficient is -0.034 ±0.006ppm/°C (I.e typically +/- 0.00294 seconds/day/°C). |
