After extensive testing — including the aluminum foil test, a reliable field demonstration of ultrasonic power — this unit outperformed comparable units in the Otto Frei lineup and surpassed less powerful models from other manufacturers, producing noticeably more perforations in the foil and demonstrating superior cavitation energy.\u003c\/p\u003e\u003cp\u003eBuilt for the demands of busy jewelry shops, this ultrasonic is engineered to cut through greasy polishing compounds quickly and completely, reaching into the tightest recesses of complex jewelry pieces. Industrial-grade transducers operating at 40 KHz and 150 watts of power make this machine a serious tool for professional metalsmiths, jewelers, and bench technicians who depend on thorough, fast cleaning cycles throughout the workday.\u003c\/p\u003e\u003cp\u003eControls are straightforward analog design — simple to operate and easy to service. German-made illuminated on\/off switches govern both the heater and the ultrasonic function, while a German-made timer allows cycle control from 0 to 30 minutes. The thermostatically adjustable heating element lets you dial in your preferred working temperature across a wide range for optimal cleaning performance. A stainless steel lid is included.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIndustrial transducers for professional-grade cleaning power\u003c\/li\u003e\n\u003cli\u003e40 KHz ultrasonic frequency\u003c\/li\u003e\n\u003cli\u003e150 watts of operating power\u003c\/li\u003e\n\u003cli\u003eThermostatically adjustable heater — 86°F to 185°F (30°C – 85°C)\u003c\/li\u003e\n\u003cli\u003eGerman-made timer (0 – 30 minute range) and on\/off switches\u003c\/li\u003e\n\u003cli\u003eIlluminated on\/off switches for heater and ultrasonic\u003c\/li\u003e\n\u003cli\u003eStainless steel tank and lid construction\u003c\/li\u003e\n\u003cli\u003eOperates at 90 decibels\u003c\/li\u003e\n\u003cli\u003e1-year manufacturer's warranty; 2-year warranty on transducers\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\u003e1.5 gallons \/ 6 quarts \/ 5.7 liters\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\u003e150 watts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNoise Level\u003c\/th\u003e\n\u003ctd\u003e90 decibels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTemperature Range\u003c\/th\u003e\n\u003ctd\u003e86°F – 185°F (30°C – 85°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTimer Range\u003c\/th\u003e\n\u003ctd\u003e0 – 30 minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTank Dimensions\u003c\/th\u003e\n\u003ctd\u003e11-3\/8\" L x 5-7\/8\" W x 5-7\/8\" deep\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOverall Dimensions\u003c\/th\u003e\n\u003ctd\u003e13\" L x 6-1\/2\" W x 11-1\/4\" deep\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConstruction\u003c\/th\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eControls\u003c\/th\u003e\n\u003ctd\u003eGerman-made analog timer and switches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e1 year (unit); 2 years (transducers)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBest Built 1-1\/2 Gallon Pro Ultrasonic unit\u003c\/li\u003e\n\u003cli\u003eStainless steel lid\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Best Built","offers":[{"title":"Default Title","offer_id":43582154014934,"sku":"123.415","price":785.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/best-built-1-12-gallon-pro-ultrasonic-otto-frei-1.jpg?v=1719957215","url":"https:\/\/www.ottofrei.com\/products\/best-built-pro-ultrasonic-1-5-gallon-150w-40khz","provider":"Otto Frei","version":"1.0","type":"link"}
