Latest DCS SUPCON WebField ECS-100 or XINHUA TiSNet-XDC800B

"Made in China" may not always be a sign of "JUNK" but buyers of many companies have discovered that some Chinese items that are specified as "metal" often are "POT METAL" -- a melting-pot combination of many metals whose origins may be recycled trash metals. Those unfamiliar with "Pot Metal" need to get knowledgeable: it usually is a low-melt combination that is easily pour-molded, inherently weak in strength, very soluble in even slightly corrosive water (Example: easily disintegrates in slightly chlorinated water!), can be plated and made to APPEAR to be brass or copper. What is the source of this junk? Much comes from the USA, junked computers and components, autos, boilers, whatever. If the surface of your item is easily scratched, be very cautious! Standards, QA and QC may not be really an established part of the Chinese industrial (and sales) system. The above has broader inferences than just the DCS SUPCON mentioned.
