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 measurement conditions (good measurement 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. Please allow a slight deviation in the measurement data and make sure you do not mind before ordering. High quality store for you! Shop tips: 1. The size is measured manually, please allow the error (1-3 cm). 2. Due to the different pixels of the monitor, there may be some color difference, please refer to the actual product.
