Product Details

A hydrometer is a necessary component of the beer making process that allows homebrewers to adjust and predict the integrity of their recipe by providing accurate readings of the beer's sugar level as well as its specific gravity.

A blown-glass hydrometer has a narrow, lengthy stem and a weighted bottom that is bulbous enough to allow for flotation purposes. Inside the stem lies a scale that measures specific gravity, or the weight of the beer compared to the normal weight of pure water. Using this kind of measuring device tells the homebrewer how far along the beer has progressed in the fermentation process so that any necessary adjustments can be made before irreversible problems arise.

Using this device is a convenient and affordable way for homebrewers and winemakers to:

  • *Approximate an alcohol percentage potential when yeast pitching is occurring
  • *Estimate alcohol percentage by comparing before and after rates
  • *Accurately determine the completion of the fermentation process or when it needs to stop

What is the Specific Gravity Scale?
Floating this device in plain water will give you a specific gravity of 1.000, which is near the top of the scale. Because the majority of hydrometers are made to reflect accurate readings at around 60 degrees Fahrenheit, water that is slightly cooler or warmer may show varying but similar readings.

Placing this meter into sugary fruit juice, or any other liquid containing sugar, will cause it to float higher than it did in plain water. For example, testing one gallon of water containing two pounds of dissolved sugar reveals a specific gravity rate of around 1.068. You can find this number by searching for the number 60 on the scale (which actually means 1.060) and determining at which tick mark the reading stops.

What is the Potential Alcohol Scale?

The potential alcohol reading of your beer is provided by the specific gravity reading. Rolling the meter around until you reach the PA scale gives you a nine percent PA reading. This means that if you fermented all of your beer's sugars into alcohol, the result would give you a nine percent alcohol rate (according to volume).

Using a hydrometer also allows you to discover the actual rate of alcohol in your finished beer batch by providing your first and last fermentation readings. Simply subtract the final fermentation reading from your first fermentation reading and you will know the percentage of alcohol in your beer.

So nice
This is a perfect little hydrometer and it comes with a full conversion chart for gravity.

Finnicky, takes practice, may just not work well.
I clean and sterilized before using on my first 2.5 batch and noticed immediately it doesn't draw or work as smoothly as my 2 year old non magical, regular siphon for 5 gal batches. But, I figured with more liquid it would draw to the fermentation bucket. It completely failed at that crucial moment and of course I stirred up sediment and spit beer everywhere while failing to make it work. I resorted to quickly grabbing, cleaning, and sterilizing my regular siphon.

This morning while giving it another clean it took some practice to make it work and even then doesn't work well. You have to draw really slowly, and back up the cane if it stops drawing liquid. If you pull too quickly water (or beer) will shoot out of the top.

I'm probably not going to risk using this again. Maybe mine is defective, maybe the design is bad. I dunno. My first mini siphon.

Still in one piece
I didn't break it yet, and the calibration was nearly spot on.

Easy to use
Best thing about this is the size of the scales. Numbers are large enough to read easily.

Broke my old one... this works like a champ...

As expected
Product does as it is intended and arrived on time. Tracking the package was easy.

What's the bulb weighted with? Is it lead, steel shots or mecury?
H F on Nov 16, 2015
BEST ANSWER: I know its not lead or mercury or any other toxic metal. They are a metal alloy and are nonhazardous. Cheers! James J.
The video for this item shows the gravity being read at the point where the meniscus touches the hydrometer sides. Usually, hydrometers are read below that point. Is this hydrometer calibrated to be read at the top of meniscus, as shown in the video?
Donovan L on May 27, 2016
BEST ANSWER: Normally you would read it below the meniscus. The correct point is roughly 0.001 higher on the scale.
Just to confirm, is this hydrometer calibrated for 60 degrees?
A D on Feb 23, 2016
BEST ANSWER: Yes, it's calibrated for 60 degrees. There are various online calculators to help correct for this, but the difference is slight. 1.051 measured at 70 degrees is actually 1.052, for example. At 80, it's actually 1.053. -Mike W, Northern Brewer
What ranges of specific Gravity does this product read? This is very important to know.
H I on Jan 15, 2016

The range is .985- 1.160


What are SKU7412 dimensions...I'm looking for small with a matched testing tube& thief.
B U on Sep 21, 2015
BEST ANSWER: The hydrometer is roughly 11" long. All our test jars about 13" tall.
Can the hydrometer gives the reading of gram/litre.
R A on Sep 4, 2015
BEST ANSWER: The hydrometer will read a gravity scale

a potential alcohol scale

and a brix scale. Here is a calculator to convert it though: http://www.calculator.org/property.aspx?name=specific%20gravity
