Tested head-to-head against comparable units using the aluminum foil test, this machine produced noticeably more perforations — a direct indicator of superior cavitation energy. For busy jewelry shops that need to remove greasy polishing compounds from tight settings and intricate metalwork quickly and completely, this unit sets a high bar at its size and price point.\u003c\/p\u003e\u003cp\u003eDigital controls are illuminated and straightforward: a power button, a heater on\/off button, and a timer button that cycles through 1-, 3-, and 5-minute cleaning intervals. Continuous mode is intentionally omitted — 95% of ultrasonic cleaning is accomplished within the first 30 seconds, and limiting run time protects delicate items from over-exposure. The built-in heater reaches up to 149°F (65°C), and warm solution consistently produces the best cleaning results.\u003c\/p\u003e\u003cp\u003eIdeal for personal use, front-counter display cleaning, or as the first professional-grade ultrasonic in a small shop.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIndustrial transducers for maximum cavitation power\u003c\/li\u003e\n\u003cli\u003e40 kHz operating frequency\u003c\/li\u003e\n\u003cli\u003e50 Watts of ultrasonic power\u003c\/li\u003e\n\u003cli\u003eIlluminated digital control panel with 3-button interface\u003c\/li\u003e\n\u003cli\u003eDigital timer with three preset cycles: 1, 3, and 5 minutes\u003c\/li\u003e\n\u003cli\u003eBuilt-in heater with maximum operating temperature of 149°F (65°C)\u003c\/li\u003e\n\u003cli\u003eHeater and power functions independently controlled\u003c\/li\u003e\n\u003cli\u003eStainless steel tank construction\u003c\/li\u003e\n\u003cli\u003eOperates at 80 decibels\u003c\/li\u003e\n\u003cli\u003e100–120V \/ 50–60 Hz power input\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eCapacity\u003c\/th\u003e\n\u003ctd\u003e1 Quart \/ 1.2 Liters \/ 0.25 Gallon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFrequency\u003c\/th\u003e\n\u003ctd\u003e40 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower\u003c\/th\u003e\n\u003ctd\u003e50 Watts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVoltage\u003c\/th\u003e\n\u003ctd\u003e100–120V \/ 50–60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSound Level\u003c\/th\u003e\n\u003ctd\u003e80 Decibels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax Heater Temp\u003c\/th\u003e\n\u003ctd\u003e149°F (65°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTimer Settings\u003c\/th\u003e\n\u003ctd\u003e1, 3, and 5 Minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTank Dimensions\u003c\/th\u003e\n\u003ctd\u003e5-3\/8\" L x 6\" W x 2-1\/2\" Deep\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOverall Dimensions\u003c\/th\u003e\n\u003ctd\u003e6-3\/8\" L x 7\" W x 8-1\/4\" H\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTank Material\u003c\/th\u003e\n\u003ctd\u003eStainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e1 year manufacturer's warranty; 2 years on transducers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDo not place items directly on the tank bottom.\u003c\/strong\u003e Always use a basket.
