EISCO Universal Laboratory Hydrometer in Hard Plastic Case- Measure Specific Gravity Range 0.700 to 2.000-0.01 Graduations - Dual Scale for Light and Heavy Liquids

I use this to check the specific gravity of my clay and glaze

Bought this and a graduated cylinder for testing liquid ceramics glazes. I haven't tested it on glazes yet, but I did check the calibration in water (accurate), and I'm very pleased with its readability and ease of use. It came in a sturdy plastic storage tube with foam on both ends to encase the hydrometer, so I'm relieved that it's pretty portable too. I will update if I encounter any problems with its intended use, but so far, 5 stars.

Works perfectly

I should have read about the size...I didn't realize it would be so big. I am using if for mixing pottery slip and so I have gotten a large plastic "tube" to pour the slip into so I can use this hydrometer. It works very well now that I have figured out how to measure the slip out of the bucket I have it in.

First Hydrometer arrived with a broken top, and the second I had to get ordered for replacement arrived with a shattered body. I should be getting paid for the time out of my day. I was excited for this hydrometer because of the range of SG it offers, but I think I’ll need to look elsewhere.

Paired perfectly with the graduated cylinder I purchased from Amazon (250ml Graduated Cylinder, Borosilicate 3.3 Glass, Single Metric Scale, Class B, Karter Scientific 213I13).

Muy bonito y bien guardado en su empaque

In a 1.25 g/cm^3 solution, the tube floats high enough that it leans sideways in an open tank. When it floats at an angle like that, it is a bit difficult to get an accurate reading.
