2L Digital Ultrasonic Cleaner Adjustable Heating Timing Cleaning Machine Features: Ultrasonic cleaners are microprocessor-controlled devices that use ultrasonic or high-frequency sound waves to clean jewelry and other delicate objects. Ultrasonic cleaning is based on cavitation caused by high-frequency ultrasonic vibration signals in the fluid.Tiny bubbles that swell and collapse quickly cause cavitation, which creates an effective cleaning effect on the surface of a cleaned object.In addition, bubbles are small enough to penetrate tiny cracks, thoroughly and consistently cleaning them. High operating frequency increases ultrasonic activity. Cleaning time and temperature are electronically controlled. Due to the ultrasonic work, indirect heating and heating of the tank will speed up the ultrasonic cleaning process. Application: Service line, electronic wire, pharmaceutical line, laboratory, machine line, scrub alloy line, chemical line. Industrial and mining enterprises, laboratory of scientific research unit, colleges and universities; hospital; electronic workshop assembly line; watch and glasses shop, jewelry shop, family.You will use ultrasonic cleaner anywhere.
