Tank volume, frequency and heat, read for what goes in the basket · review
A compact 400 ml ultrasonic cleaner working at 48 kHz, with a digital display of the cleaning time, automatic switch-off at the end of the set time and a detachable lid, whose listing publishes no power figure.
The bottom line A small, simply described cleaner with a stated frequency and a timed switch-off. Without a power figure or a timer range it cannot be compared closely with the others, and it says nothing about what may go in the tank beyond water.
Five bullets: 48 kHz ultrasonic cleaning with millions of micro-bubbles, using plain tap water on jewellery, glasses and dentures; a light 304 stainless steel build with a waterproof coating and four rubber feet; uses at opticians, laboratories, jewellers, watch shops and at home; a 400 ml tank, one-button operation, a digital time display, automatic switch-off at the set time, a detachable lid and a power cable; and lifetime customer service.
Frequency is the one acoustic figure on this page. Higher frequencies produce smaller cavitation bubbles, which is why the figure is worth publishing. The listing gives the frequency and not the power that drives it.
The first bullet names tap water. It neither permits nor forbids detergents or solvents, so the maker’s manual is the reference before adding anything to the tank.
Power, a timer range, a basket and a drain. For a 400 ml tank the drain matters little — it can be emptied by hand — but the basket keeps small parts off the vibrating floor.
At the last look-up, the German Amazon store was asking roughly 25 €.
The French, Italian and Spanish Amazon catalogues list the product, yet no seller was offering it.
The American and British Amazon stores returned no entry, so the buy button there opens a search rather than a missing page.
