LogTag TRID Refrigeration Monitoring

Powerful TRID Logger Tracks the Cold

LogTag TRID Refrigeration MonitoringTRID represents the state of the art in self-contained refrigeration monitoring systems. TRID is a display logger that provides detailed information of the recent thermal history of its monitoring results with simple button presses.  That is good, but TRID also preserves all of this information for archival and proof purposes using download to a PC.

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 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.

Two models are available: (7F) permanent battery installed with 3 years of battery life or (7R) user replaceable with 1 year per installation battery life
