Range: The range will change according to the different versions of the model, the actual range is indicated in the outer packaging of the machine.Accuracy: it can reach the nominal range under good measuring conditions (good measuring surface, ambient temperature, interior lighting). Under bad measurement condition, such as excessive light, weak reflection on the surface of the measured object, or excessive temperature difference, the error will increase.Tips: Please use cutting board or better reflective surface when sunlight or target is not reflective.
