BAOSHISHAN NO.1 Zahn Cup Viscosity Cup #1 Dip Type 44ml Stainless Steel Viscometer Flow Cup for Paint Finishes Oil Dye Sauce Honey

The product is well packaged and very easy to operate

Easy to use and clearly marked. Just will with your favourite fluid and watch it go thorough the opening at the bottom. You can then calculate whether it is within range. Pretty smart device.

Il faut revoir le control et la qualité, il y a pleins d'arrêtes coupantes au niveau de la poignés et de la louche là où il y a du soudage. Ça ne réflète pas la valeur suggéré avec pleins de défaut partout.

It's really a nicely made cup, and the inaccuracy isn't BAOSHISHAN 's fault, it's inherent to the nature of Zahn cups in general. It's a really imprecise way to measure viscosity, but coatings manufacturers continue to spec using Zahn cups, so until they come into the 21st century there's not much we can do about it. This cup is pretty nice, and after a couple of pulls to get back in the habit, I can get a set of readings that repeat within about 15%. Which is about as good as I've ever done. It does read about 20-30% higher than another cup I have here, but that doesn't surprise me at all given what the old cup has been through. These numbers are probably better. Although I've had numbers jump around by 30% or more when using different brand cups in the past, so I just consider the Zahn readings to be one of several data points to consider in determining if a coating is appropriately thinned. I mostly use the readings as a starting data point, and then to help maintain consistency through batches. (As long as one considers +/- 10-15% to be consistent :-). ) Enough bellyaching, back to this review - good product at a fair price!

I use this when I spray my crafts, No more guessing on wether the liquid will spray in my LPHV gun.
