Ultrasonic Cleaner

An ultrasonic cleaner is a cleaning device that uses ultrasound (usually from 20–400 kHz) and an appropriate cleaning solvent (sometimes ordinary tap water) to clean delicate items. The ultrasound can be used with just water, but use of a solvent appropriate for the item to be cleaned and the soiling enhances the effect. Cleaning normally lasts between three and six minutes.
Ultrasonic cleaners are used to clean many different types of objects, including jewellery, lenses and other optical parts, watches, dental and surgical instruments, tools, coins, fountain pens, golf clubs, window blinds, firearms, industrial parts and electronic equipment. They are used in many jewellery workshops, watchmakers' establishments, and electronic repair workshops. 
Maintenance Guide:
1 Ultrasonic Scaler's main components
Current clinical use of ultrasonic scaler models mostly piezoelectric effect, which is characterized by power, heat and there is a small spray device. It mainly consists of an ultrasonic generator, transducer, working head and foot pedal of four parts.
2. Precautions and maintenance when use
(1) preoperative testing should be processed after power is turned on, the power transferred at medium power (power symbol number from 1 to 4, the small power of 2.0,the power of 3.0, power is about 4.0), then step the foot switch, and to regulate the frequency table, so that the deflection of the needle indicates the maximum value (usually60 ~ 80μA), then if the first contact work surface, you see a lot of mist spray, indicating ultrasonic vibration.
(2) In the process of cleaning teeth, scaler tips must spray to point contact of dental calculus, do not apply excessive pressure. Tips should also be frequently changed, to prevent damage by heat generator and transducer.
(3) Ultrasonic scaler does not apply to patients with a pacemaker installed, because such patients susceptible to interference from surrounding electromagnetic radiation induced vertigo, epilepsy, heart rhythm disorders, which requires the physician, should be asked in detail about preoperative 
medical history.
(4) Ultrasonic scaler transducer and tips should not be boiled and soaked in disinfectant, should be placed in special sterile instrument in disinfection, so as not to damage the transducer.
(5) Ultrasonic scaler and tap water is generally connected device, so at least a week to cover the water network within the cleaning device 2 or 3 times, with waterproof rust clogging.
