Hi there, it's my first post on the forum so please excuse me if I get something wrong! Anyway, I needed a small and very cheap ultrasonic cleaner to clean some PCB's and other small mechanical parts. I didn't want one of those jewellery cleaners you can buy at some craft shops but a proper ultrasonic cleaner. I opted to buy this model from eBay :
http://www.ebay.co.uk/itm/301391234616_trksid=p2057872.m2749.l2649&var=600367375531&ssPageName=STRK%3AMEBIDX%3AITIt purchased the 3.2L capacity model as this is all I needed really, the item arrived quickly (2 business days) from a Chinese seller with a wear house in the UK. The unit is made from stainless steel, and isn't overly heavy but it isn't lighter than I would expect either. It has the ability of heating the water up to 80°C via a 100W heating plate, and has two 60W ultrasonic transducers. As with all cheap things from china I was dubious about it's safety as it's powered via 240V, made of sheet metal and holds 3.2L of water, a potential recipe for disaster if not engineered correctly. I decided to crack it open, and I was pleasantly surprised to see it was put together decently (nothing special but adequate), earthing was done properly and the PCB looked decent. I have included the photos i took of the internals and externals of this unit.
It preformed well, and removed flux residue and corrosion very well. It takes a while to heat the water up (20Min) but that is to be expected with a 100W element, you can just have the water heater on by itself if required. It is however very noisy and I certainly cant be in the same room as it when it is in operation.
Let me know what you think
