LogTag® TREL30-16 - 30 day display with external probe

Applications

Monitoring of articles stored at very low temperatures such as in dry ice type environments, where a remote probe is beneficial.

 

Product Summary

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.

Remote Probe Options

LogTag® TREL is designed and calibrated for use with the LogTag® ST10S remote temperature probe. Only this probe is compatible with TREL and using any other probe type is likely to cause an error in readings.

LogTag® ST10S sensors are designed and calibrated for interchangeability with TREL loggers to the standard rated accuracy of the product. If a TREL/ST10S probe combination is calibrated to a higher level of accuracy (as is possible) then care should be taken to always use the same TREL/ST10S combination for measurements as the ST10S sensor is not rated interchangeable at accuracies better than the TREL/ST10S rating in this specification.

Identifying an ST100 probe

The ST10S probe is distinguished from other LogTag® remote temperature probe types by the green sleeve color on the sensor’s plug.



ST10S-05 (0.5m)
ST10S-30 (3m)

Short tipped probe

The tipped probe incorporates a 22mm exposed length of 5mm OD 316 stainless probe without handle but with small over mold to improve resistance to moisture and provide cable strain relief.
All materials at probe end of cable are FDA food rated including the cable.
Supplied standard (part# ST10S-05) with 0.5m or extended (part#ST10S-30) with 3m cable terminated to MCX plug for plugging into LogTag® TREL.
