| Product Model | TREX-8 | 
| 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 for -10°C to +40°C. Better than ±0.7°C for -10°C to -30°C and +40°C to +60°C.
 Better than ±0.8°C for -30°C to -40°C and +60°C to +80°C.
 Better than ±1.0°C for +80°C to +99°C.
 Actual performance is typically much better than the rated values. Please see the Rated Absolute Accuracy chart below.
 Accuracy figures can be improved by recalibration.
