Feature? 1. The handpiece is cast from titanium alloy to ensure sound mechanic function and durability. 2. Assembling with excellent piezo- ceramic, the handpiece has high and long lasting power and generates little heat. 3. The cable is made from silica gel tube, soft and durable. 4. N1 is attached with sealed handpiece. 5. The material made in America is appointed material of aero plastic components in Europe and America, which is FDA and NSF certificated. 6. Five pieces scaling tips attached, 2 piece of G1#, 1 piece of G2#, 1 piece of G4# and 1 piece of P1#.The scaling tip is made of special material. The cavitation produced from the end of the scaling tip makes the cleaning of teeth and the killing of germ easy. 7. Automatic frequency tracking ensures that the machine always work on the best frequency. 8. The adjustment range of the amplitude is much wider than before. 9. To eliminate the dental calculus, bacterial plaque, tea scales on the teeth quickly without hurting the gum and the enamel. 10. Small and light designed easy operation.
