50kHz Ultrasonic Cleaner for Small Items

The Metra S910 is a 50kHz ultrasonic cleaner with a 350ml stainless steel tank. It uses high-frequency sound waves to create microscopic bubbles that clean jewellery, eyeglasses, watches, dentures and similar small objects. The unit is designed for portable use at home or in a professional setting. It includes a power adapter and a user manual.

Simple Operation with Three Timer Settings

Place items in the tank with cold water, select one of the three timer modes (3, 5 or 10 minutes) and start the cycle. The machine runs automatically and stops when the time elapses. Using hot water or skipping the recommended cold water can reduce cleaning performance. Heavily soiled pieces may require running a second cycle for full results.

Check Tank Size and Material Compatibility

Verify that your items fit inside the 350ml tank before ordering. Ensure the materials are safe for ultrasonic cleaning with cold water; certain gemstones, glued settings or fragile antiques may be damaged. The cleaner requires a standard mains outlet for the supplied adapter. No special installation or plumbing is needed.

Questions about this item

How do I verify the S910 is cleaning properly after I set it up?

The 50kHz ultrasonic waves create millions of microscopic bubbles that reach every crevice; you will see dirt lift off jewellery, eyeglasses or watches within a 3, 5 or 10 minute timer cycle, leaving items visibly cleaner.

What comes in the box with the Metra S910 and is anything else required?

The package includes the ultrasonic cleaning machine, a power adapter and a user manual; you only need to add cold water to the 350ml stainless steel tank before starting a cycle.

Which version of the S910 should I choose for cleaning multiple items at once?

The single 350ml capacity model with 50kHz frequency and three timer modes is the only version offered, and its large tank lets you clean several pieces of jewellery, dentures or razors simultaneously.
