DIY Must-have: Track the quality of your home produce

When hearing the words “density measurement”, many people think of it as some complicated analysis method used in laboratories and industry. While it is true that density measurement is a powerful tool for industry, it can be really useful for DIY (do it yourself) fans too – especially for those who like producing their own food and drinks.

Let me tell you where I use my EasyDens, the world’s smallest digital density meter, at home and what I am able to find out. I apply density measurement not only in my kitchen where I measure my homemade products but also in my garden to find out about the water quality of my pool or do a quick check on my car’s cooling system.

1: Do you like freshly squeezed fruit juices, smoothies, or home-made syrups? Measure the sugar content of your DIY drinks.

I am a big fan of fruit juices and syrups – my favorite one is homemade apple juice. When producing your own juice or syrup it is important to get the amount of sugar right. Nobody wants to drink sour juice, right? In order to ensure it always tastes the same, I measure the sugar content in °Brix with EasyDens during the process.

But not only the sugar content in juices is easy to determine; did you ever wonder how much sugar there is in maple syrup or honey? Maple syrup has around 65 to 68 °Brix, so 65 to 68 grams of sugar per 100 grams of syrup. Honey even ranges from 70 to 88 °Brix. Do you want to try measurements like these?

2: Do you experiment with DIY beer in your kitchen? Do fermentation control.

Standing in your kitchen to make your own wine or beer can be a lot of fun. But it is even better when the outcome is exactly as you intended it to be. I control the fermentation progress of my beer with density measurements every day – that is the way I can see if my product is fermenting too fast or too slow and whether I have to change any conditions.

3: Give your fish a cozy home: Control the water quality of your aquarium.

In my opinion, the most beautiful fish live in seawater. If you want to bring them into your home, you need a salt water aquarium. In order to keep the fish alive and happy it is important to ensure the best water quality. A crucial parameter for this is the salt concentration, which should be 3.6 % as in seawater. Using density measurement you can check whether there is enough or too much salt in your aquarium.

4: Concentration measurement of alcohols

Distilled spirits enjoy growing popularity. As a great DIY fan, I started to create my own spirit at home. After deciding on which spirit to make, collecting enough fruits, fermenting them, and distilling, the homemade spirit is finally ready. There is one question left: what’s the alcohol per volume? With a density meter this parameter can be measured quickly – a value between 37.5 and 43 %v/v alcohol is most common for spirits.

But did you know alcohol is not only in spirits but a different alcohol is added to cooling liquids too? These glycols prevent the cooling agents freezing when they are exposed to cold temperatures in winter. They are applied universally in cars and in solar collectors. To be frost-proof to -20 °C the liquid should have a density of approximately 1.05 g/cm³. Whenever you have a density meter at hand you can easily determine the concentration of alcohols in your cooling agent and you will know whether it will survive the cold winter.


EasyDens – how and what to measure

SG (specific gravity)

Control your brew’s fermentation by a daily measurement of specific gravity using EasyDens and enjoy your delicious beer afterwards.

%w/w extract

Use %w/w (weight per weight) extract to find out the apparent extract content of your DIY beer. For the right instrument for this, have a look here.

%v/v alcohol

Measure the alcohol content (in % volume per volume) of your freshly distilled spirit with the portable alcohol meter Snap 40.

Now you know how density meters can be used at home.
