The LogTag® TREL30-16 Temperature Recorder measures and stores up to 15,900 temperature readings over a -90°C to +40°C (-130°F to +104°F) measurement range from associated interchangeable LogTag ST10 remote probe temperature sensor (available in lengths up to 3 metres (9’10”).
The display is designed to show ‘at a glance’ if temperature excursions have occurred during the current day and up to the previous 29 days. The display also shows the current temperature reading, the current time, recording status and battery status.
The alarm is triggered if temperature readings are outside pre-set alarm limits. The status indicator changes from a ✓ to a ✗ and, if configured, the audible alarm will sound. The day marker will also appear if not already present.
The alarm status indicator and audible alarm can be easily cleared, but the day marker remains to ensure a visible record of excursions is shown on the display. A simplified alarm clearance, stop & start procedure is available as an option.
Details of any excursions in the preceding 30 days can be checked directly by inspecting the statistics history on the recorder’s display or in more detail by downloading the logged data via a standard LogTag Interface cradle to LogTag Analyzer operating software.

|Rated Temperature Reading Accuracy||Better than ±0.5°C for -20°C to +10°C (-4°F to 50°F).|
Better than ±0.7°C for -50°C to -20°C (-58°F to -4°F) and +10°C to +30°C (50°F to 86°F).
Better than ±1°C for -80°C to -50°C (-112°F to -58°F) and +30°C to +40°C (86°F to 104°F).
Better than ±1.8°C for -90°C to -80°C (-130°F to -112°F ).
Actual performance is typically much better than the rated values.
Accuracy figures can be improved by recalibration.
|Rated Temperature Reading Resolution||0.1°C (0.2°F) for measurements -80°C to 0°C (-112°F to 32°F).|
0.2°C (0.4°F) for measurements 0°C to 18°C (32°F to 64.4°F) and −90°C to −80°C (−130°F to −112°F).
0.3°C (0.5°F) for measurements 18°C to 30°C (64.4°F to 86°F).
0.5°C (0.9°F) for measurements 30°C to 40°C (86°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®.
