600ml Ultrasonic Cleaner 48000Hz

The Metra SU-743A is a compact ultrasonic cleaner with a 600ml stainless tank that operates at 48000Hz. It targets home users who want to clean jewellery, eyeglasses, watches and small metal parts without manual scrubbing. A digital timer offers five preset cycles ranging from 90s to 480s and the unit shuts off automatically when the cycle ends. A cleaning basket is included to hold delicate items during operation.

Home users cleaning jewellery and small items

This cleaner suits anyone who regularly cleans rings, necklaces, spectacles, razor heads or small tool parts at home. The five timed modes cover light to intensive cleaning without guesswork. It is not for buyers who need a heated tank, degassing function or industrial throughput. Workshops requiring continuous operation or larger volumes should look at larger-capacity equipment.

48000Hz frequency with five digital timer presets

The single specification that decides fit is the 48000Hz ultrasonic frequency combined with the fixed digital timer presets of 90s, 180s, 280s, 380s and 480s. If your cleaning routine matches these exact intervals and you do not need adjustable power or heat, the SU-743A matches the requirement. Buyers needing variable frequency, temperature control or longer cycles will need a different model.

Questions about this item

How often should the cleaning solution be replaced in the 600ml tank?

Replace the solution when it looks cloudy or after several cleaning cycles, as dirt and oils build up in the 600ml capacity tank.

What is the longest single cleaning cycle the digital timer allows?

The timer offers five preset modes up to 480 seconds, so the longest automatic run is 480 seconds.

How much heat does the SU-743A generate during a full 480-second cycle?

The unit produces only a soft buzz and mild warmth during operation; the 48000Hz vibration cleans without significant heat buildup.
