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.

|Storage Temperature Range||-10°C to +55°C (14°F to +131°F).|
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.
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®.
