Source: lrultrasonics.com (verified 2026-08-01). ADDED TO EXPAND ROSTER: L&R Quantrex is a long-established, industry-standard brand among US jewelers and watchmakers, filling the professional/trade tier alongside Branson and Elmasonic that a serious 2026 buyer would compare. Manufacturer page states 95W consumption without the heat option and 150W with it engaged; heater_watt is left null because L&R does not publish a separate heater-only rating (the 55W arithmetic difference is not a directly-stated figure, so per the null-beats-a-guess rule it is not recorded). Tank material and digital-display status not specified on the accessed page (Quantrex tanks are stainless steel across the broader product line per L&R's general literature, but this was not explicitly confirmed on this specific product's page, so left null).
