LogTag® TRED30-7 - Temperature Recorder with 30 day summary display and remote probe

Applications

All standard temperature recording applications where an external probe is beneficial and where recorded data needs to be accessed without a PC.

Product Summary

The LogTag® TRED30-7 Temperature Recorder measures and stores up to 7770 temperature readings over -40°C to +99°C measurement range from a remote temperature probe.

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 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 recorder’s display or in more detail by downloading the logged data via a standard LogTag® Interface cradle to LogTag® Analyzer.

If a reading outside the pre-set “Alarm” limits is recorded at any time, a “day alarm indicator” appears on the display.

  • Flexible recording options Either record for a fixed time or record continuously with ‘wrap around logging’
  • Rapid Download! Takes only seconds to download recordings.
  • Thin flat case Fits easily into packaging and thin enough to be easily mailed “letter rate”
  • Real time clock Records time & temperature simultaneously
  • 7770 recordings capacity Enough memory for 53 days @ 10min logging or 80 days @ 15min log
  • High Quality Connector Gold plated remote sensor connector
  • Interchangeable Probes LogTag® remote temperature ST100 probes are interchangeable.

 

Display

The normal recording display shows the current temperature reading, the time and the alarm trigger day summary. A visual alarm trigger is displayed if one or more of the configured alarm trigger conditions have been met. An alarm trigger condition can be a single reading above the upper or below the lower threshold values, a set of consecutive violating readings or an accumulation of violation readings encountered.

These display examples show alarm triggers recorded 1,8, 20, 21 and 26 days ago. Review each day’s statistic by pressing the REVIEW button.

Statistics include the maximum and minimum reading for each day, durations above or below preset thresholds and alarm stati.

The recorder can be configured to suspend processing of readings for alarms and max/min statistics for a period of time after button press activity.
This allows the user to review the current statistics or clear an alarm without causing a false alarm or statistic while handling the recorder.

Remote Probe Options

LogTag® TRED30-7 is designed and calibrated for use with the LogTag® ST100 remote temperature probe. Only this probe is compatible with TRED30-7 and using any other probe type is likely to cause an error in readings.

LogTag® ST100 sensors are designed and calibrated for interchangeability with TRED30-7 loggers to the standard rated accuracy of the product. If a TRED30-7 /ST100 probe combination is calibrated to a higher level of accuracy (as is possible) then care should be taken to always use the same TRED30-7/ST100 combination for measurements as the ST100 sensor is not rated interchangeable at accuracies better than the TRED30-7/ST100 rating in this specification.
