Range: The range will change depending on the different versions of the model, the actual range is indicated in the outer package of the machine. Precision: It can reach the nominal range in good measuring conditions (good measuring surface, ambient temperature, interior lighting). In poor measuring conditions, such as excessive light, a low reflection on the surface of the measured object or an excessive temperature difference, the error will increase. Tips: Please use a cutting board or a better reflective surface when sunlight or target are not reflective.
