????[Function：Pulse] Continuous tracking to the resonant frequency for a long time to achieve peak output of ultrasonic power. The actual performance is that the ultrasonic continuous impact the items, enhance the effect of ultrasonic cleaning. ????[Function ：Sweep] In general, the ultrasonic distribution of traditional machines may not be able to throughout the tank, resulting in small ultrasonic power in some areas.Sweep function can make a uniform distribution of the ultrasonic power throughout the tank, to meet higher cleaning requirements. ????[Function ：Degas] Air in the liquid affects cavitation and reduces ultrasonic power.Degas can quick degassing of cleaning liquids,the resistance of bubbles produced by ultrasonic cavitation reaction will reduced and the ultrasonic cleaning effect will be better. ????[Function ：Adjust power] Can adjust power 40%-70%-100%.Third generation(V1.3) digital ultrasonic control cleaning system,more intelligent.The machine of use will be more stable and more powerful,low noise. ????[Note]Tank material :SUS304 1MM Tank size: 3L(0.79 gal)/238*138*100mm(9.37*5.43*3.93inch); Basket size: 218*120*65mm(8.58*4.72*2.55inch), its about 2.5L for water (when its filled to the very top). please according to your needs to buy and avoid the size not fit your need.
