Range	Resolution	Accuracy
-50°C to 0 °C (-58 °F to 32 °F)	0.1 oC/°F	+ 4°C/+ 7°F;
0°C to 350°C (32 °F to 662 °F)		± 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 valueField 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.
