Dry Ice Ultra-Low Temperature Data Logger

The LogTag® Dry Ice “Probe-less” Temperature Logger operates, measures and stores up to 8000 temperature readings in temperature environments ranging from -80°C to +40°C (-112°F to +104°F). Intended for use in transit monitoring of articles stored in packaging incorporating dry ice cooling agents.

The LogTag® Dry Ice Temperature Logger is easily configured for recording conditions including delayed start, sampling interval, number of readings and configuration of conditions to activate the ALERT indicator.

FEATURES:

• Records temperature from +40°C to as low as -80°C
• Up to 8,000 recordings – enough for the longest trip.
• In-transit inspections can be recorded at the push of a button.
• A real time clock provides date/ time stamps for each temperature reading.
• Push-to-start button with optional delay or a specific time & date.
• Comprehensive customization options including alarm settings, sample interval and trip duration.

Rated Temperature Reading 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 Temperature

Reading 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),
