TREL-8 is a remote temperature logger using a replaceable ST10 probe (up to 3 meters long), measuring and storing up to 8000 temperature values in the range of -90°C to +40°C. The device is suitable for monitoring goods stored in low-temperature environments such as dry ice. It offers flexible configuration options: delayed start, sampling interval, and over-limit alerts. Data is downloaded and analyzed via the free LogTag® Analyzer software, which supports graphing, statistics, and data export to Excel. A red light indicates over-limit warnings, while a green light confirms normal operation without requiring a computer connection.
| Product Model | TREL-8 |
| External 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 ±1.0 °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) Better than ±1.2 °C (±2.1 °F) for +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) 0.2 °C (0.4 °F) for measurements -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® |
