External Sensor Measurement Range | -40°C to +99°C (-40°F to +210°F) |
Operating Temperature Range | -40°C to +85°C (-40°F to +185°F). |
Storage Temperature Range | -10°C to +55°C (14°F to +131°F). |
Rated Temperature Reading Accuracy | - Better than ±0.5°C (±0.9°F) for -10°C to +40°C (14°F to +104°F).
- Better than ±0.7°C (±1.3°F) for -30°C to -10°C (-22°F to 14°F) and +40°C to +60°C (104°F to 140°F).
- Better than ±0.8°C (±1.4°F) for -40°C to -30°C (-40°F to -22°F) and +60°C to +80°C (140°F to 176°F).
- Better than ±1.0°C (±1.8°F) for +80°C to +99°C (176°F to 210°F).
- Actual performance is typically much better than the rated values.
- Accuracy figures can be improved by recalibration.

Rated Temperature Reading Resolution | - Less than 0.1°C (0.2°F) for measurements -40°C to +40°C (-40°F to +104°F).
- Less than 0.2°C (0.4°F) for measurements +40°C to +80°C (+104°F to +176°F).
- Less than 0.6°C (0.5°F) for measurements +80°C to +99°C (+176°F to +210°F).
- LogTag Analyzer®currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag®.
