Review on North Mountain Supply Glass Hydrometer by David Pirlet

Seems to work. But since it's not exactly what I thought, I order another one and compare the readings to 2. Some say the readings are inaccurate, some say everything is fine, but I can't verify, I can't tell whether it's true or not. 't. The case it comes in won't work for you as a test glass if you plan on testing more reliable stuff. First thoughts are that since the description wasn't entirely accurate, I have to question the witness testimony as well. Save and compare with others. If they match, I use it somewhere (maybe in a big pot or jar where I don't need a test jar) or it ends up in the trash. If I had known about these issues, I probably would not have ordered.
