VEVOR Ultrasonic Cleaner with Digital Timer & Heater, Professional Ultra Sonic Jewelry Cleaner, Stainless Steel Heated Cleaning Machine for Glasses Watch Rings Small Parts Circuit Board (3L)

Compact 240x135x100mm Tank Built for Jewelry and Small Precision Items 

The 3L ultrasonic cleaner interior measures 240x135x100mm — a size deliberately suited to individual items and small batches rather than bulk processing. Rings, earrings, watch parts, eyeglass frames, dentures, and small circuit boards all fit without being crowded, so the cleaning solution can reach every surface during the cycle.

Long-term exposure to hot detergent solutions does not rust or break down the SUS304 stainless steel structure. At every turn, the tank remains completely sealed because the leak-proof integral frame has no weak seam joints. Using the basket that comes with it, you can keep things off the tank floor. This keeps both the items and the tank lining from wearing down due to direct contact.

3L Ultrasonic Cleaner with 40kHz Frequency Optimized for Delicate Item Cleaning 

This 3L ultrasonic cleaner is the right size for items that need accuracy over strength, like jewelry with fine engravings, optical lenses, very delicate watch gears, and small dental tools. The 40kHz frequency works well for this task because it creates fine, dense cavitation that moves slowly over delicate finishes and intricate surface features without stirring them up too much.

With cavitation, you can get to small gaps, recesses, and surface features that contact-based tools can't, all without touching the thing you are working on. At the end, even the most fragile pieces are clean, with no scratches, chemical damage, or risk to the finish or structure.

120W Power with 2 Piezoelectric Transducers for Consistent Cavitation 

Two sandwich-type piezoelectric transducers produce a total of 120W of ultrasonic energy. This output has been precisely calibrated for the 3L tank volume to ensure the cavitation energy is evenly distributed throughout the cleaning solution. This setup helps ensure that items placed anywhere in the small tank receive the same level of cleaning power in every cycle, without any hot stains or weak stains that could lead to uneven results. The transducers are calibrated for the 3L tank volume to clean as effectively as possible at the right power level for this tank's size.

The 120W output is a good match for the 3L volume. It is strong enough to remove oil, wax, stains, and stubborn particles from complex surfaces and deep grooves, yet gentle enough for delicate items like eyeglasses and jewelry. This non-contact cavitation cleaning system helps remove dirt from delicate surfaces with minimal risk of scratching. It works the same way every time, whether it is at home, in a dental office, or in an optical workshop.

170W Heating Element with 0–80°C Adjustment for Faster Contaminant Removal 

Users can precisely change the liquid temperature from room temperature to 80°C using the built-in 170W heating element. This lets them create the optimal cleaning environment for the type of contamination they are treating. Higher temperatures make liquids less thick, cleaning agents work better, and grease, oil, and organic residue break down faster. This means that each cycle cleans more thoroughly and faster. The heating and ultrasonic functions work together for faster cleaning without long preheating delays.

The LED panel displays the temperature in real time throughout the process, allowing users to monitor it. While cold-water ultrasonic cleaning would require much longer exposure times to achieve the same results, this heating feature works especially well on items like dental tools, carburetor parts, and kitchen cutlery that have hardened grease or biological residue. The 3L capacity and 170W heating power work well together to get to the right temperature quickly without wasting energy on extra space.

Compact Digital LED Panel for Easy Time and Temperature Control 

The digital control screen makes it easy and accurate to adjust all the machine's settings without a complicated setup. You can adjust the cleaning time between 0 and 30 minutes and set the target temperature to match the item type and level of contamination. The LED panel shows the current time and temperature during each cycle, so users can see everything at a glance and do not have to guess or check by hand while the machine is running.

Adjustable time and temperature settings allow different cleaning intensities based on item type. An easy-to-use interface makes it quick and simple to set up and run a full cycle at home or at work. At 2.95 kg and 10.4" x 6.3" x 8.9", the unit is very light and easy to move around and put on any desk, service bench, or countertop without taking up valuable space. 

3L Ultrasonic Cleaner Ideal for Personal Care, Optical, and Dental Use

The 3L capacity makes this unit the right choice for settings where cleaning needs are consistent but compact — a jewelry counter, an optical shop station, a dental prep area, or a home cleaning setup. It handles daily cleaning of rings, necklaces, eyeglasses, contact lens cases, dentures, and watches without taking up valuable counter space.

At 2.95kg and small enough to sit on any shelf or service bench, it delivers professional cleaning results in a footprint that larger units cannot match. For anyone who needs reliable, precise cleaning every day without dedicating a full workstation to it, this 3L ultrasonic cleaner is the practical choice.
