Note:
After the sensor is powered on, it needs to be preheated for about 20s to stabilize the measured data. Heating the sensor is a normal phenomenon because there is an electric heating wire inside, which is abnormal if the hand is hot.
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
