Best Hydrometer – Top 4 Hydrometers Reviewed

A hydrometer is an instrument that can measure specific gravity of liquids or the ratio of density of a liquid to the density of water. It is usually made of glass, and has a cylindrical bulb and a stem weighted with lead shot or mercury to make it float upright.

Hydrometers are mostly used by winemakers and brewers to test samples of their products. They can be used to measure density of liquid before and after the fermentation process. The difference in the readings allows them to ascertain the product’s alcohol percentage.

Want to buy a good hydrometer for your needs. We’ve lined up the best ones available on Amazon. They are reasonably priced and provide accurate readings each time you use them.

Tips For Buying The Best Hydrometer

You have many options when it comes to buying hydrometers. You can choose from among triple scale hydrometers, thermohydrometers and precision hydrometers.

Triple scale hydrometers are the least expensive and multi-functional device that measures specific gravity, and potential alcohol. It measures a wider specific gravity range (0.000-1.165) and can be off a little bit.

The thermohydrometer can measure temperature and specific gravity. Calibrations can vary by device, but it has been built to ensure your temperature is consistent. The benefit of this device is that you get two instruments in one.

The precision hydrometer can measure specific gravity and its numbers are spaced on a smaller scale. This ensure a more accurate reading. However, its’ best to buy few hydrometers depending on your use. Some may measure between 1.000-1.060 and others 1.065-1.180. They are best if more accurate reading is important for you.

Important Things To Consider

Glass can break, especially when you’re dealing with many moving parts. Some hydrometers come with testing jars that do double duty as a case as well. Its best to buy a graduated testing jar if it suits your budget.

These days, you can also buy a “proof and tralle” hydrometer that has been designed for a much higher ABV solutions such as liquors and spirits. It is not suitable for meads, wines and beers.

Some manufactures now use a paper scale inside the glass which can sometimes slip around and may result in inaccurate readings, so make sure you choose one with a plastic insert.

The best hydrometer can be a useful tool that will save you many batches-and headaches- down the road. So, incorporate this device into your process, and all your batches will only continue to get more consistent with time.
