1. The scalers of our company have the features of strong function for cleaning teeth with safety, comfort and without heating and aching pain. Now, many other scalers have two problems during the course of cleaning teeth.

On one hand, when doctor feels there is force during cleaning teeth, the patient will produce feelings of aching pain and scorching； on the other hand：during the course of cleaning teeth, the patient may produce feelings of heating and aching pain and the doctor may fell the force of cleaning teeth is shortage and the operation has no efficiency. The F3-1 type built-in scaler produced by our company has basically resolved this problem and can make doctor with facility when using it and make patient with comfort and reliability.

2. Can resist the disinfection with 135℃ of high temperature and high pressure, the inserting type titanium alloy handle is safety, reliable and can prevent cross infection. Today, in the gradual serious condition of infectious diseases, such as SARS, hepatitis B, avian influenza and AIDS, you may be infected unconsciously when cleaning your teeth! The handle of scaler produced by our company can resist the thorough disinfection with 135℃ of high temperature and high pressure, it can effectively prevent cross infection and guarantee you comfort and safety when cleaning your teeth.

3.The function of automatically searching the optimum operation status can use any piezoelectric transducer and scaler cutter head, meanwhile, the cutter head of scaler can be used no matter how much it is worn and this is our another innovation fruit. Now, so many energy transducer and cutter head of scaler cannot be exchanged and even the exchange is realized, the working efficiency then cannot reach up to the optimum condition. The F3-1 type built-in scaler produced by our company can basically resolve this problem，it can be matched with EMS and the energy transducer and cutter head of EMS can be used on our scaler, this has thoroughly settled the exchange problem of energy transducer and cutter head of scaler. It is just because that technology makes our cutter head of scaler can be used no matter how much it is worn.

4. The working course of scaler is monitored by microcomputer automatically and the working can keep more stable.
