NSK Varios 970 / 970 LUX
NSK's top model of its compact ultrasonic-scaler series: a tabletop control unit with an LED display, three operating modes (Perio, Endo, General), two 400 ml irrigation bottles with a tap-water option, an auto-cleaning function for the irrigation lines and a Varios2 piezo handpiece. The 970 LUX has an LED-lit handpiece; the plain 970 does not. It does not include an air polisher.
