±0.25°C from -40° to 0°C (±0.45°F from -40° to 32°F) |
|
| ±0.20°C from 0° to 70°C (±0.36°F from 32° to 158°F) |
|
|
| ±0.25°C from 70° to 100°C (±0.45°F from 158° to 212°F) |
±2.5% from 10% to 90% RH typical to a maximum of ±3.5% including hysteresis at 25°C (77°F); below 10% and above 90% ±5% typical |
