I'm particularly interested if anyone has had any success with Aliexprss sort of places. I'm building prototypes of a couple of gas management devices ATM using bits from AlieX and Banggood and so far delivery times have been reasonable, about 3 - 4 weeks ex China.
Also, and sorry to brag (not really or I wouldn't do it), I finally scored an Anton Paar densitometer on Ebay on Thursday. Arrived from Thailand today, so 5 days including the weekend. Should have bought one of those robust jobbies when I started brewing. Probably smashed about four grands worth of hydrometers over the years.. |

They're not that robust. If you drop it and break the tube or even if you use the wrong cleaning agent in the tube and etch it, the thing is buggered. In the one I have the tube cannot be replaced so that's the end of it. One advantage is that you know it will cost $4k to replace so you tend to be careful.
The most recent model is a modular design and the tube unit can be bought as a repair part but I believe it's over $1k.
BTW I found a new trick up its sleeve yesterday: if I set the unit to ABV it reads accurately enough to do alcohol in wine by the "method of differences", using an Atago Pal -Tea refractomoter for the second reading.
I used the algorithm ABV = (A + 2.75 R) / 2 where A is the reading on the DMA35 and R is the reading on the refractometer.
