The LogTag® TRID30-7 temperature logger features a display together with a data logging function storing up to 7770 temperature readings. Statistical temperature and duration readings for up to 30 days can be reviewed on the display.
The visual display of current temperature and previous alarms is an important feature in “static” applications such as cool rooms and refrigerators. The TRID30-7 can also be used in transit applications where direct readout of the statistical data is required without use of a computer or readout device.
The display arrangement is designed to show ‘at a glance’ if temperature violations 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.
Details of any excursions can be checked directly by inspecting the statistics history on the loggers display or in more detail by downloading the logged data. If a reading outside the pre-set “Alarm” limits is recorded at any time, a “day alarm indicator” appears on the display.
Logged data can be downloaded via a standard LogTag® Interface to the companion software LogTag® Analyzer which provides facilities for displaying data in chart, table or statistical formats and allows electronic archiving, export or transmission of the data in support of sophisticated data management systems.
|Product Model||TRID30-7R (Replaceable Battery).
TRID30-7F (Fixed Battery).
|Sensor Measurement Range||-30°C to +60°C (-40°F to +210°F).|
|Operating Temperature Range||-30°C to +60°C (-22°F to +140°F).|
|Storage Temperature Range||-10°C to +40°C (14°F to +104°F).|
|Rated Temperature Reading Accuracy||
Better than ±0.5°C (±0.9°F) for measurements from -20°C to +40°C (-4°F to +104°F), typically ±0.3°C (0.6°F).
Better than ±0.8°C (±1.5°F) for other measurements – typically ±0.5°C (0.9°F).
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||
0.1°C (0.2°F) for measurements -40°C to +50°C (-40°F to +122°F).
0.2°C (0.4°F) for measurements +50°C to +70°C (+122°F to +158°F).
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 5 minutes (T90) in moving air (1m/s) in EN12830:1999.|
|Recording Capacity||7,770 temperature readings. 53 days @ 10min logging, 80 days @ 15min logging.
Day summary statistics memory (for display on LCD): up for 30 days of Max/Min/duration and alarm trigger statistics.
|Sampling Interval||Configurable from 1 minute to hourly.|
|Logging Start Options||Push button start (with configurable start delay from 1 minute to 18 hours) or specific date & time.|
|Recording Indication||“REC” symbol on LCD|
|Download Time||Typically less than 5 seconds for full memory (7,770 readings), depending on computer or readout device used.|
