LogTag TREL-8 – Multi-Use Low Temperature With External Probe
- Records temperature from +40°C to as low as -90°C
- Up to 8,000 recordings – enough for the longest trip
- In-transit inspections can be recorded at the push of a button
- Comprehensive customization options including alarm settings, sample interval and trip duration
Requires LT-INT-HID or LTI-Wifi Cradle (not included) to connect to a computer to read/program the logger.
The TREL-8 Low Temperature Remote Probe Logger measures and stores up to 8000 temperature readings over -90°C to +40°C (-130°F to +104°F) measurement range from associated interchangeable LogTag ST10 type remote probe temperature sensor (available in lengths up to 3 meters (9’10”).
It is intended for use in monitoring of articles stored at low temperatures such as in dry ice type environments. Using the LogTag Interface Cradle and LogTag’s freely available companion software LogTag Analyzer.
TREL-8 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.
The Red Alert indicator provides an immediate indication, without access to a PC, if any readings are outside the limits specified at the time the unit was configured. Green OK indicator provides immediate visual confirmation, without access to a PC, that the unit is operating.
Manufacturer Specs
| Product Model | TREL-8. |
| Sensor Measurement Range | -90°C to +40°C (-130°F to +104°F). |
| 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®. |

| 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 | 1 year storage, 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). |
