LogTag TREX-8 External Probe Temperature Data Logger
The LogTag TREX-8 is a compact, multi-use temperature data logger designed for use with interchangeable external probes.
Separating the probe from the recorder makes it suitable for monitoring inside refrigerators, freezers, storage areas, containers and other locations where the logger needs to remain accessible outside the monitored environment.
- External temperature measurement from −40°C to +99°C
- Stores 8,031 time-stamped readings
- Interchangeable ST100 external temperature probes
External Probe Monitoring
Position the temperature probe inside the monitored space while keeping the logger accessible outside it.
Wide Temperature Range
Measure temperatures from −40°C to +99°C across chilled, frozen and higher-temperature applications.
Configurable Alerts
Set high and low temperature limits to help identify excursions from the required operating range.
Simple Data Retrieval
Download recorded readings quickly for charting, analysis and reporting using LogTag Analyzer.
The TREX-8 is designed for applications where temperature must be measured remotely from the position of the recorder.
Typical applications include:
- Laboratory refrigerators and freezers
- Pharmacy and medical storage
- Cold rooms and refrigerated storage
- Cold chain transportation
- Food storage and distribution
- Environmental and stability chambers
- Temperature-controlled containers
- Production and processing equipment
- Temperature mapping exercises
Different ST100 probe styles and cable lengths are available to suit the equipment, monitored space and installation method.
The TREX-8 combines remote temperature measurement with flexible configuration, interchangeable probes and straightforward data retrieval.

Why Choose the LogTag TREX-8?
The LogTag TREX-8 offers an economical way to monitor temperatures remotely using an external probe, without requiring a complex continuous monitoring system.
Its interchangeable probe design makes it particularly useful for refrigerators, freezers and enclosed equipment where the sensing point and recorder need to be positioned separately. Configurable intervals, start options and alerts allow each logger to be prepared for a specific monitoring task.
Recorded data can be transferred using a LogTag interface cradle and reviewed in LogTag Analyzer, providing charts, statistics and exportable records for reporting or further investigation.
