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

| Product Model | TREL-8 |
|---|---|
| External Temperature Sensor Measurement Range | -90 °C to +40 °C (-130 °F to +104 °F) |
| Recorder Operating Temperature Range | -20 °C to +40 °C (-4 °F to +104 °F) |
| Storage Temperature Range | -10 °C to +55 °C (14 °F to +131 °F) |
| 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 |
| Sensor Reaction Time | Typically less than 2 minutes(T90) in moving air (1m/s) for ST10S type |
| Recording Capacity | 8031 temperature readings. 53 days @ 10min logging, 80 days @ 15min logging. |
| Sampling Interval | Configurable from 30 seconds to several hours |
| Logging Start Options | Push button start with optional start delay or specific date & time |
| Recording Indication | Flashing ‘OK’ indicator / flashing ‘ALERT’ indicator |
| Download Time | Typically less than 5 seconds for full memory (8031 readings), depending on computer or readout device used |
| Environmental | IP61 |
| Power source | CR2450 3V LiMnO2 Battery (Fixed) |
| Battery Life | Storage life of 1 year before ‘start’ (if it is hibernation mode), followed by: 2 – 3 years of normal use (based on 15 minute logging, download data monthly) |
| Real Time Clock | Built-in real time clock. Rated accuracy ±25ppm @ 25°C (equivalent to 2.5 seconds/day). Rated temperature coefficient is -0.034 ±0.006ppm/°C (I.e typically +/- 0.00294 seconds/day/°C) |
| Standard Remote Sensor Cable Length | Standard: 0.5m (19”). Extended: 3m (9’10”) (recommended maximum) |

| Size | 86 mm(H) x 54.5 mm(W) x 8.6 mm(T) |
| Weight | 34g |
| Case Material | Polycarbonate |
