VEVOR Knob Ultrasonic Cleaner 3L 40kHz Ultrasonic Cleaning Machine Knob Control Sonic Cleaner 304 Stainless Steel Ultrasonic Cleaner Machine with Heater & Timer for Cleaning Jewelry Eyeglasses Watches

SUS304 Stainless Steel Tank with Noise Reduction Lid for Durable Quiet Use 

The 3L tank is made of 304 stainless steel, which is highly resistant to rust, corrosion, and heat, even when used repeatedly with water based cleaners. The integrated tank design helps reduce potential leakage points during operation. Built in handles on both sides of the housing make it easy to move without spilling, even during repositioning between cleaning tasks. 

The noise-reduction lid helps reduce the sound of ultrasonic vibrations, which is useful in shared workspaces, retail counters, and home environments. It comes with an extra cleaning basket to keep sharp or rough objects away from the tank walls and to avoid damage from contact. The set includes both a regular basket and a jewelry basket to protect your belongings from damage.

Heated Ultrasonic Cleaner with 40kHz Cavitation for Contact-Free Deep Cleaning

Most cleaning methods work from the outside in. When you press a brush or cloth against the surface, you miss deeper issues and put fragile things at risk. This heated ultrasonic cleaner does the opposite of what most do. At 40kHz, the cleaning solution begins to work, creating dense cavitation that penetrates blind holes, threaded spaces, and uneven surfaces where dirt builds up, all without touching the item at all.

The fact that frequency and heat work together from the beginning of the cycle is what makes this so efficient. Fine and controlled bubble action at 40kHz makes it a good choice for jewelry, eyeglasses, watches, dental tools, and small metal tools where the finish is important. It cleans delicate items well without damaging them, and it works just as well on highly dirty professional parts. They both benefit from the same non-contact process, which gives the same result every time. 

120W Industrial-Grade Transducers for Powerful, Consistent Cavitation 

Two professional piezoelectric transducers work together to deliver 120W of ultrasonic energy through the 3L tank, distributing the cavitation energy evenly. This setup helps ensure consistent cavitation exposure throughout the tank. This eliminates weak spots that cause uneven cleaning results. It is well calibrated for the tank's size, so the transducer output cleans as well as possible without generating harmful noise.

The 120W output is strong enough to remove oils, waxes, oxidation, and biological residue from complex surfaces and hard-to-reach internal geometry, yet gentle enough for fine jewelry and eyeglasses. The non-contact cleaning action can reach long channels, threaded recesses, and gaps that manual tools cannot reach. It cleans the surface to a level that traditional contact-based methods rarely reach in the same amount of time.

Mechanical Knob Control with 20–80°C Range for Simple Heated Cleaning 

You can easily control the timer and liquid temperature by turning two simple mechanical knobs. The interface is purposely simple so you can use it quickly and correctly without menus or digital input. The timer can be set up to 30 minutes, and the temperature can be adjusted from 20°C to 80°C. This lets users customize cleaning settings to match the type of contamination they are dealing with.

High temperatures make it easier to remove tough grease and wax buildup, speed up detergent action, and improve overall cleaning effectiveness per cycle. Heating and ultrasonic cleaning can operate simultaneously, reducing overall processing time. The simple knob controls allow quick adjustments during operation.

Dual Fuse Protection and Heat Dissipation Vents for Safe Extended Operation 

Safety features are integrated throughout the design. Multiple heat-dissipation holes on both sides of the housing allow passive airflow to continue during use. This keeps the electronics inside from overheating during long cleaning sessions. In normal use, the design prevents the unit from overheating without active cooling components, extending its overall service life.

Two fuses provide overcurrent protection, and an extra fuse is included in the package so it can be used right away if needed. This helps reduce downtime in professional settings where the machine is always on. The unit stays in place on any work surface thanks to four non-slip rubber feet, even when the ultrasonic machine is vibrating. The heated ultrasonic cleaner is reliable during long shifts in dental clinics, optical shops, maintenance workshops, and labs, thanks to its safety and stability features.

Heated Ultrasonic Cleaner CE-Certified for Jewelry, Dental, and Lab Use 

It has CE approval, which means that this heated ultrasonic cleaner meets European safety standards for use in business, industry, and homes. Many different types of businesses trust it. Jewelers use it to clean rings, necklaces, brooches, and diamond jewelry; optical shops use it to clean eyeglasses and sunglasses, and watchmakers, antique dealers, and hardware stores use it to clean precise parts.

For people who use it at home, it regularly handles watches, silverware, coins, and other everyday items. Its small size (10.63" x 6.69" x 9.45") means it can fit on any counter or service bench without taking up a lot of room. When used multiple times a day at work or occasionally at home to clean personal items, this VEVOR unit consistently cleans thoroughly and without scratches across all supported applications.
