The LogTag® TREL30-16 Temperature Recorder measures and stores up to 15,900 temperature readings over a -80°C to +40°C (-112°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 trigged 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.

Actual performance is typically much better than the rated values. Please see the Rated Absolute Accuracy chart below.
Accuracy figures can be improved by recalibration.
|Rated Temperature Reading Resolution||
Less than 0.1°C for -80°C to 0.0°C
Less than 0.2°C for 0.0°C to +20°C
Less than 0.5°C for +20°C to +40°C
Please see the Rated Native Resolution chart below.
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.|
|Sampling Interval||Configurable from 30 seconds to hourly.|
|Logging Start Options||Push button start or specific date & time. Optional start delay of up to 18 hours.|
|Recording Indication||State indicator “REC".|
|Download Time||Typically less than 10 seconds for full memory (15,905 readings), depending on computer or readout device used.|

NOTE: Typical battery life assumes 6 minute logging, day statistics are reviewed on the display no more than once daily for no longer than 30 seconds each time.
Download data monthly.
NOTE: Continual activation of the audible alarm will reduce the working life of the battery. When an alarm is triggered, the alarm should be cleared and reset as soon as possible.
