The LogTag® Low Temperature Remote Probe Recorder measures and stores up to 8000 temperature readings over -90 °C to +40 °C measurement range from associated interchangeable LogTag® ST10 type remote probe temperature sensor (available in lengths up to 3 meters).
Intended for use in monitoring of articles stored at low temperatures such as in dry ice type environments.
Using the LogTag® Interface and LogTag’s freely available companion software LogTag® Analyzer, the LogTag® is easily configured for recording conditions including delayed start, sampling interval, number of readings and configuration of conditions to activate the ALERT indicator.
Readings are downloaded using LogTag® Analyzer which provides facilities for charting, zooming, listing data statistics and allows exporting the data to other applications such as Excel.
Please note: An interface is required for configuration and reporting

Rated Temperature Reading Accuracy |
With the logger case sitting in an environmental temperature between 0 °C and 50 °C. Better than ±1 °C (±1.8 °F) for -30 °C to +20 °C (-22 °F to +68 °F). Better than ±1.2 °C (±2.1 °F) for -45 °C to -30 °C (-49 °F to -22 °F) and +20 °C to +40 °C (+68 °F to +104 °F). Better than ±1.7 °C (±3.1 °F) for -80 °C to -45 °C (-112 °F to -49 °F). Better than ±2.0 °C (±3.6 °F) for -90 °C to -80 °C (-130 °F to -112 °F). Actual performance is typically much better than the rated values. Accuracy figures can be improved by recalibration. |
Rated Temperature Reading Resolution |
0.1 °C (0.2 °F) for measurements -80 °C to 0 °C (-112 °F to 32 °F) 0.2 °C (0.4 °F) for measurements 0 °C to 18 °C (32 °F to 64.4 °F), and -90 °C to -80 °C (-130 °F to -112 °F) 0.3 °C (0.5 °F) for measurements 18 °C to 30 °C (64.4 °F to 86 °F) 0.5 °C (0.9 °F) for measurements 30 °C to 40 °C (86 °F to 104 °F) LogTag Analyzer® currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag |
