DA-20 adopts piezoceramic ultrasonic technology, which uses high-frequency and high-energy vibrations generated by ultrasonic waves to clean the surface of the teeth, break up calculus and stains in the periodontal pockets by tips, and then the rubble and plaque are washed down by the water spray produced by the device. The irrigation system inside the product is made of anti-bacterial materials. The liquids used in clinics, such as hydrogen peroxide, chlorhexidine, sodium hypochlorite, etc. Can be applied in the mode of automatic water supply system, which can significantly improve the performance of teeth cleaning and root canal washing.. The handpiece can be sterilized at 135? Temperature and 0.22 MPa pressure. Automatically search for the best working condition, the performance of device is more stable. The device has a built-in computer microprocessing chip, which can intelligently control the working power and make treatment more comfortable. The wireless foot switch is used to remotely control the unit, which is more convenient to operate. At the same time, wired foot switches can also be selected according to user needs. High-brightness LED, which can improve the efficiency of clinical operation, and it can also use ordinary plug-in handpiece that has high compatibility. Input Voltage:220 V±22 V~ , 50/60 Hz. Batteries of wireless foot switch:AA Batteries×2. Receiving sensitivity: -114 dB, receive frequency:2.4 G-2.5 G. Tip amplitude: minimum, 1? M, deviation -50%. Maximum, 100? M, deviation +50%. Half deflection force:minimum, 0.1 N, deviation -50% maximum, 5 N , deviation +50%. Vibration frequency of tip:18 kHz~45 kHz. Note:The vibration frequencies of different types tips are different, but they are all distributed within the described range. Output Voltage of tip:3 W~20 W.
