Ultrasonic Jewellery Cleaner 400ml

The Metra SU-708 is a compact ultrasonic cleaner with a 400ml SUS304 stainless steel tank. It targets dirt in hard-to-reach gaps on rings, eyeglasses, watch straps and small accessories using high-frequency sound waves and an LED blue light. Three preset cycles of 180, 300 and 480 seconds cover routine cleaning tasks for home or light professional use.

Check Tank Dimensions and Cycle Lengths

Verify that your largest items fit inside the internal tank measuring 8.24 by 3.59 by 2.65 inches. The machine offers only the three fixed cycle times listed above with no adjustable timer, so confirm those durations suit your typical workload. Note that oxidation discoloration will not be removed by this process.

Upgrade From Manual Soaking or Smaller Tanks

This unit replaces hand scrubbing and basic soaking baths that cannot reach tight crevices. The jump is worthwhile when you regularly clean multiple small items and want repeatable, hands-free cycles. It is not suited for buyers who need larger capacity, variable timing or heated ultrasonic cleaning.
