Mid-range (33 KHz) offers a balance suitable for general-purpose use. Higher frequencies (40 KHz) generate smaller, gentler bubbles ideal for delicate components such as PCBs, optical lenses, and fine jewellery, minimising the risk of surface damage.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is sweep mode and why does it matter?\u003c\/h4\u003e\n\u003cp\u003eA: Sweep mode continuously varies the operating frequency by ±1 KHz around the set point. This eliminates ultrasonic \"dead zones\" — areas in the tank where standing waves cancel out cavitation — ensuring every part of your load receives consistent, uniform cleaning energy regardless of its position in the tank.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this ultrasonic cleaner for jewellery and electronics?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The multi-frequency capability makes it versatile across both applications. Use the 40 KHz setting with a suitable cleaning solution for jewellery and circuit boards, and switch to 28 KHz for heavier items like carburettors or dental instruments. Always check the manufacturer's guidelines for the specific items you are cleaning.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the Granbo GL0610 compatible with my local mains voltage?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The unit supports both 110 V and 220 V input, making it compatible with electrical standards in North America, Europe, Australia, and most other regions worldwide — no separate transformer required.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How loud is this machine during operation?\u003c\/h4\u003e\n\u003cp\u003eA: The Granbo GL0610 features sound-insulation cotton lining inside its enclosure, which significantly reduces the high-frequency noise typical of ultrasonic cleaners.
