Read the two power figures correctly
The US TH-SPQXJ-100A page distinguishes 600W ultrasonic power from 1200W heating. Its tank interior is listed as 530 × 325 × 200 mm, with 40kHz operation and a zero-to-30-minute timer. These are configuration details; none is a measured cleaning-performance result.
The newer 30L knob-control listing is a separate comparison: it lists a zero-to-90-minute timer and explicitly distinguishes nominal class from working water level. Choose between them by the control sequence and load requirements, keeping each model’s specifications together.
Modes do not replace material checks
The manufacturer advertises degassing for preparing the liquid and a gentle setting for lower-power operation. We do not adopt its percentage improvement claim as a measured result. No independent performance test accompanies this buying note.
Reduced output should not be treated as clearance for a fragile setting, coating or bonded assembly. First establish whether the item maker permits ultrasonic cleaning at all. The useful role of a selectable mode is to adjust an already appropriate process, rather than rescue an unsuitable item from the wrong method.
Plan around the actual basket
The US specification table reports a 530 by 325 by 200 mm tank interior and a zero-to-30-minute timer. Basket clearance is not established in our source record. The tank measurement is shown for comparison, but our fit tool cannot turn it into a confirmed basket fit.
A sensible shortlist starts with the largest routinely cleaned item and the number of parts you want to process separately. Consider whether a smaller bath can handle those tasks without crowding. Choose this larger model when its documented configuration and additional controls justify the space, solution volume and setup involved. Confirm the current manual and electrical requirements of the ordered unit before use.
Before you choose
- Basket interior remains unverified.
- Gentle mode does not establish material compatibility.
- The manufacturer’s percentage efficiency claim is not independently validated here.
