Description

Take the guesswork out of measuring your final gravity.

Precisely read the finishing gravities in your homemade beer with this narrow-range, highly accurate hydrometer. The scale range is only .990-1.020, but the individual gradients are extra large making it easy to read.

I like the smaller scale on the FG hydrometer. I am hoping that this device will improve the accuracy of my FG readings.
Ryan B on Jul 8, 2019

Vernon L on May 31, 2019
Because I feel like breaking another one of these. But my old eyes can't read the final gravity well on the standard hydrometer
Glenn H on May 16, 2019
The previous one I had snapped on the long skinny tube, and I like the easier to read scale

I am developing a house yeast, and I need to ensure accurate FG.

I had one before and loved it. However, it broke in transport.

This hydrometer did not come with a temperature guide. I was wondering what the temperature of the liquid should be at?
Steven Grant on Mar 6, 2018
BEST ANSWER: The paper scale in this hydrometer says 15.6° C and 60° F.
What is the calibration temperature of this hydrometer? Is it 60F or 68F? The MoreBeer online tool only mentions the Triple Scale Hydrometer, not the Final Gravity Hydrometer.
Roderick on Jul 28, 2020
BEST ANSWER: I have purchased the Final Gravity Hydrometer and mine is cal @ 60. They are very fragile.

Works well if you are looking for more accuracy on FG. Comes with a protective tube to help stabilize the top when storing.

I may have ordered the wrong hydrometer. Just brewed a batch of beer that said estimated original gravity should be 1.066-1.070. This hydrometer only goes to 1.020. Maybe this one is not designed for beer?

Good, but delicate
There is plenty of room between numbers for accurate final gravity readings. No more worrying about the meniscus and guessing between a few points. Still, as others have mentioned, it is really delicate. The stem is so thin, I would not pick it up that way, and definitely wouldn't hold it by the stem at any sort of angle. Still, if you're careful it should give you good service, and the lack of guesswork will make it worth the investment.

Great resolution
I love this hydrometer. It has so much better resolution. Only worried about how thin the top is (handle with care or it could break).

Doesn't come with graduated cylinder
I would rate this 5 stars if it came with its own graduated cylinder.I tried using the one from my regular hydrometer, but this final gravity hydrometer is slightly wider and sticks to the sides of the cylinder. For $22 bucks it should include it's own plastic cylinder.
