±2% of reading or ±2ºC /±4°F

Note:

 Accuracy is given at 18°C to 28°C (64°F to 82°F), less than 80%RH.

Emissivity: 

0.95 fixed value

Field of View:

 Make sure that the target is larger than the unit’s spot size. The 

smaller the target, the closer you should be to it. When accuracy is critical, 

make sure the target is at least twice as large as the spot size.
