TREX-8

Temperature data logger with external probe -40°C to +99°C

All standard temperature recording applications where an external probe is beneficial.

The LogTag® TREX-8 is a versatile, wide range, multitrip Temperature Logger with interchangeable External Probes, featuring high resolution temperature readings

Using the LogTag®  Interface and the freely available companion software LogTag® Analyzer , the LogTag® is easily set-up for recording conditions including delayed start, sampling interval, number of readings, continuous or fixed number of readings and configuration of conditions to activate the ALERT indicator.

Applications

Cold Chain – Pharmaceuticals – Produce/Meat/Dairy – Agriculture & Floral – Office & Warehouse – Museums – Chemicals – Laboratories – Server room – Clinical trials
