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