content: Hi folks,I wanted to know who makes this Asita MD321 Multimeter. I'm asking because I already have one of their Multimeters (the MD591), which has now become my main portable Multimeter. I bought it on a flea market a while back for cheap just because it had Autoranging. But has since become my favorite, its accuracy and speed are very good. Words can't describe it, but the way the multimeter performs is incredible. Only things that are missing from this one is the lack of TRMS and Capacitance range is only up to 200uF. I do have a Fluke 179 but still prefer the Asita for everyday hobby use.Anyway, the MD591 impressed me, was a bit dubious on how a fairly "unknown" Italian brand could deliver such an exceptional product and was looking to find out who the manufacture actually was. A bit of googling lead me to nothing, so I went and opened it. And there was a marking "732". A quick search and there it was, mystery unsolved... the MD591 was actually a Yokogawa 732 (732-02/03), and then everything made sense. It was a Japanese quality and rightfully so I could feel the difference, even with better Chinese quality (Uni-T for example).Problem is I've never seen any other MD591 coming up for sale on flea markets, but I see often its smaller brother, the MD321. I actually had bought one just because, but then later gave it to a friend who has told me he is happy with it. I've been doing a bit of searching on the internet, but can't seem to find another Yokogawa model that matches the MD321. The styling is very similar to the its bigger brother (the MD591) but still can't point it accurately its a Yokogawa product or not. Perhaps something else? On the ASITA website they sell rebranded Hioki's as well.I was looking to buy one, just to keep around, you know, as a backup or something, or just as a banger in case I want to test something that even if smth goes wrong I wouldn't worry much. And wanted to get one if its a Japanese model, I have plenty of cheap-o dmms from China. Does anyone recognize the MD321?I've seen it also branded as a Wurth 0715 53 432. Any info is well accepted. Thanks in advance and sorry for the long message, hopefully I got it all explained in shortest possible way.

I guess where is made isn't that important nowdays, its just the how the brand designs and expects the product to be build. Apple products come to mind, those are made in China but designed by Apple and meet the Apple standards.

content: The plot thickens as it seems I have found yet another Multimeter that is basically the same as the Asita MD321: ... the DER EE DE-200A.There seems to be a Japanese guy on YT that has shown the insides of the DER EE one, build quality seems ok-ish, was expecting better though:

content: from ebay offer pictures of 732https://www.ebay.com/itm/374035439475so it would seem that they use an OEM in Taiwan for those (pretty common for lot of manufacturers)
