Scope: The scope will vary according to different versions of the model, and the actual scope is indicated on the outer packaging of the machine. Accuracy: The nominal range can be achieved under good measurement conditions (good measurement surface, ambient temperature, room lighting). Under unfavorable measurement conditions such as too strong light, low surface reflectivity of the measured object, or too large temperature difference, the error will increase. Tip: When sunlight or targets are not reflective, use a cutting board or a better reflective surface.
