It works great, and I like the fact that it doesn’t break if you accidentally drop it

The plastic construction is very rugged - far greater durability than glass. The only disadvantage is the hash marks on the hydrometer are somewhat hard to read.

Nice addition
Definitely a good item for wine making. Gravity readings are much more accurate. Haven’t figured out how to use ABV scale on this yet but this was my first batch of wine.

Calibration Way Off
I like that it is more durable than the glass versions, but it is unusable. The problem is that the paper inside containing the scale is not fixed, so it moves around. This makes it impossible for consistent and accurate measurements. The finished gravity for my last beer was 0.988. In distilled water it reads 0.984, which is 0.016 (2.1% ABV) off from the 1.000 it should be.

Highly recommend
Highly recommend. I've gone through so many of the glass ones that break if you look at them the wrong way. I wish I'd found this one sooner.

Should say: do not fully immerse in water
Seems plenty sturdy but I'm disappointed that it isn't fully sealed like the glass ones. There is a little plastic plug at the top that doesn't completely seal out liquids if you fully immerse it when sanitizing it, which I suspect would throw off the readings (due to more weight inside) if you don't then remove the plug and let it completely dry out inside.

How accurate would the reading be if the sample is over 60F?
A shopper on Jun 21, 2018
BEST ANSWER: After drawing your sample, take several readings as the temperature falls in the beaker and note the difference. The closer you are to room temperature the more accurate it is. I finally bought a refractometer and it's more accurate, plus it doesn't waste so much product.
Can you test gravity in crude oil with this?
A shopper on Oct 12, 2017
BEST ANSWER: No, this is meant for beer and wine.
will it measure alcohol contents in liquor?
A shopper on May 15, 2017
BEST ANSWER: Not quite. This hydrometer has a limited range, ( for beer and wine use ) and stronger alcohol bases are usually measured with a different hydrometer, the "Proof and Tralle Hydrometer" - that's the one you want for high-alcohol measurements. See part # 7442 on our site.
what is the diameter of the tube? Will it fit in the fermentech wine thief? I have a 1.020-.98 hydrometer and it doesnt fit well in the fermentech thief.
Gwynn D on Nov 8, 2016
BEST ANSWER: I use my hydrometer with a 12-inch plastic test jar, and it fits nicely. Sorry I can't confirm the Fermentech thief as a good fit.
