350ml 48KHz ultrasonic cleaner

The Metra BCM-197 is a compact ultrasonic cleaner designed for jewellery, watches, eyeglasses and small metal items. Its 350ml tank and 48KHz frequency suit home users who want professional-grade cleaning without harsh chemicals.

350ml capacity with three preset timers

The 350ml tank holds rings, necklaces and watch bands for cycles of 180s, 360s or 540s. It handles everyday grime and oxidation well, but larger bracelets or multiple heavy pieces may exceed the usable volume.

Included adapter, cloth and touch controls

A power adapter and soft cleaning cloth ship in the box, so the unit runs immediately. Touch operation and auto shut-off simplify the process, while the digital display confirms the selected cycle at a glance.

Questions about this item

Will the 48 kHz frequency clean my watch bands without harming the spring bars?

The 48 kHz ultrasound creates microscopic bubbles that reach into band links and clasp crevices, removing grime without abrasive contact on spring bars or pins.

How do I confirm the 24 W ultrasonic power is running during a cycle?

The smart digital display shows the active timer countdown — 180, 360 or 540 seconds — and the unit emits a faint hum while the transducer is energised.

Does the box include cleaning solution or only the machine and accessories?

The package contains the ultrasonic cleaner, a power adapter and a cleaning cloth; cleaning solution is not included and must be purchased separately.
