What is the "direct" and "indirect" cleaning of ultrasonic cleaners?
Direct cleaning usually refers to the cleaning of the workpiece in a cleaning tank filled with cleaning liquid. The workpiece is usually packed in a tray or basket with holes
When selecting indirect cleaning, make sure that the water level in the tank is maintained at the standard position.
The indirect cleaning is to place the workpiece to be cleaned in a beaker or a tray without holes, and a solution is provided in the beaker or tray instead of being directly installed in the cleaning tank
The limitation of direct cleaning is the need to select cleaning fluid that will not damage the ultrasonic cleaning tank
