Crest 275 Ultrasonic Cleaner Tru-sweep 275HT Heated with Timer - 3/4 Gallon

Crest has brought the superior performance of full-wave 38.5 kHz industrial transducers to the Tru-Sweep line. What's more, all units are supplied with either 0-30 minute analog or 0-99 minute digital timers. And the heaters are thermostatically controlled.

Crest's exclusive Tru-Sweep feature ensures uniform cleaning throughout the tank by sweeping the ultrasonic frequency +2kHz, creating overlapping ultrasonic waves. This eliminates inconsistent cleaning due to hot spots caused by the unvarying or "standing" waves produced by conventional ultrasonic power supplies.

When ultrasonic energy is introduced into a cleaning solution, cavitation, the foundation of ultrasonic cleaning, occurs. Ultrasonic energy causes alternating patterns of low and high pressure phases. During the low pressure phases, bubbles, or vacuum cavities, form. In the subsequent high pressure phases, these bubbles implode violently. This is called cavitation.
