Do not touch the measuring tools of aluminum plate with wet hands

Aluminum plate may need welding, cutting and other operations because of the different places used in the industry. These operations may require measuring tools to accurately measure the required welding and cutting dimensions. How to deal with the tools after measurement? Does it also need maintenance like aluminum plate? Are there any special requirements for the storage place? Firstly, the storage place of measuring tools shall be kept clean and dry, free of vibration and corrosive gas, and shall be far away from places with large temperature variation range or places with magnetic field. The measuring tools stored in the measuring box shall be clean and dry, and other sundries are not allowed to be stored.
