Storage Temperature Range | -10°C to +40°C (14°F to +104°F). |
Rated Temperature Reading Accuracy | - Better than ±0.5°C for -20°C to +10°C (-4°F to 50°F).
- Better than ±0.7°C for -50°C to -20°C (-58°F to -4°F) and +10°C to +30°C (50°F to 86°F).
- Better than ±1°C for -80°C to -50°C (-112°F to -58°F) and +30°C to +40°C (86°F to 104°F).
- Better than ±1.8°C 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®.
