Final Gravity Hydrometer

Final Gravity Hydrometer

Item currently out of stock

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 got mad that my filter “package” didn’t come with a mounting brackett and through my hydrometer against the wall. !! J/k

Hard to find item, that is very useful

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
more accuracy
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
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.

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.

Use for all FG readings
Sometimes gravity readings on hydrometers can be challenging to read. This hydrometer makes taking a FG reading very simple. The larger scale means a more precise reading. I highly recommend this hydrometer to anyone looking to determine the FG of their beer.

Accurate and easy to read
This will make for easier and more accurate final gravity readings, if I’m careful with it and don’t snap the neck. Very fragile.

Very precise, very delicate
With greater precision comes greater delicacy! Don't kid yourself about this! THIS IS A VERY PRECISE, DELICATE INSTRUMENT! This is not the proper tool for your brew day activity. Use it when your fermentation is near or at completion.

Be focused & careful when it comes to this stage of brewing. DON'T SHORTCUT OR BECOME HASTY!

If you are prone to breaking hydrometers, purchase 2!

Take your time & be extremely careful & this tool will provide you with a precision report on your final gravity. It does for me, every time!
