With an ultrasonic power top output of 100 watts on average and a frequency of 45 kHz with a sweep of +/- 1.5 kHz The Powersonic P500D-45 ultrasonic cleaning unit comes with a 2 year parts and labor warranty. Crest's Powersonic rugged industrial-strength performance gives you consistent quality at a bench top price. Crest's exclusive Powersonic feature ensures uniform cleaning throughout the tank by sweeping the ultrasonic frequency 3 kHz, creating overlapping ultrasonic waves. This eliminates inconsistent cleaning due to hot                                                       spots (areas of intense ultrasonic activity) in the cleaning solution, caused by the                                                             unvarying or "standing" waves produced by conventional   ultrasonic power supplies.
