Features: 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 Five pieces scaling tips attached: 2 pieces of G1#, 1 piece of G2#, 1 piece of G3#, 1 piece of P1#. 5 The scaling tip is made of special material. The cavitation produced from the end of the scaling tip makes the cleaning Of the teeth and the killing of the germ easy. 6 Automatic frequency tracking ensures that the machine always works on the best frequency. 7 The adjustment range of the amplitude is much wider than before. The new style solenoid valve can control the water better. The new style water control switch makes the adjustment of the water more convenient. To eliminate the dental calculus, bacterial plaque, and tea scales on the teeth quickly without hurting the gum and the enamel. Small and light designed, easy operation.
