About scaler units
The powered unit and its handpiece, which drive the vibrating tip. A piezoelectric scaler has a negative feedback function that automatically adjusts the output power based on the resistance the working tip meets. There is no uniform method for quantifying the output power of a machine, which makes two machines of the same stated power hard to compare.
The unit that generates the vibration, as against the tips and accessories that fit it. A rotary scaler does the same job differently: it is an abrasive device attached to a powered handpiece to remove calculus deposits, also Class II (21 CFR 872.4840).
