How does a antifreeze hydrometer work?
The hydrometer tests ethylene glycol on a temperature scale from -51°C to 0°C (-60°F to 32°F), indicating whether the solution is properly mixed to prevent freezing.
How do you measure antifreeze concentration?
The only accurate way to test for this concentration (and freeze point) is to use a refractometer. The old-style floating ball testers will not work properly with modern OAT, NOAT, and HOAT formulations. Generally, there are two types of refractometers that you should use with your modern coolant mixtures.

What should my antifreeze reading be?
4 volts or less means the coolant is good. Replace the coolant if the reading is higher than . 4 volts. If you think the only job of antifreeze (coolant) is to cool the engine during the summer and prevent freeze-up during the winter, read on.

What is the correct ratio of antifreeze to water?
50:50Mixtures with a ratio of 50:50 work almost in every climate. In climates where temperatures drop below 0℃ for a longer period, mixtures closer to 60% antifreeze and 40% water are better suited to keep coolant from freezing.
Should antifreeze be tested hot or cold?
Sometimes the best thing to do when you notice a change in the temperature gauge is to pull over and wait for things to cool off. Driving with a hot engine can do more harm than good, so we'd always recommend allowing things to cool down before checking the coolant/antifreeze reservoir.
What happens if coolant is too concentrated?
Mixtures with too much water may not provide adequate boil over or freeze protection. Mixtures with too much antifreeze concentrate may actually cause over heating. This is due to the fact that the antifreeze alone is not very efficient at absorbing the heat from the engine with out water mixed with it.

How do I know if I have enough antifreeze?
Generally, low and high markings on the side of the plastic overflow bottle connected to the cooling system tell you if there is enough coolant in the engine. The coolant level should be between the two marks.

What information can the cooling system hydrometer give you?
By using a hydrometer, you can test the strength of your existing antifreeze. A hydrometer allows you to draw a small amount of coolant from your system and shows you the freezing point of your coolant.

How does a hydrometer work?
A hydrometer operates according to the Archimedes principle stating that a solid-state body displaces its own weight with a liquid in which it floats. The liquid to be tested is poured into a tall specially designed cylindrical container, and the hydrometer is gently lowered into the liquid until it freely floats. There is a point at which the surface of the liquid touches the stem of the hydrometer. This point is noted as the reading point.
What is a hydrometer used for?
You might already know that a hydrometer is a device that is used to measure the specific gravity, or in other words, the relative density of liquids. And that is a good start, but do you know how to use and read a hydrometer?
Why should a hydrometer be at the same temperature?
Temperature: In order to avoid changes of density during testing, the hydrometer and liquid should be at the same temperature as the ambient temperature.
Why is it important to clean the hydrometer?
Cleanliness: It is very important for the liquid to uniformly rise merging into an almost invisible film on the stem. Therefore, hydrometer surface, stem, the hydrometer jar, and the liquid in which the readings are taken should be properly cleaned.
Where can you read a hydrometer scale?
You can now read the hydrometer scale at the lowest point of the liquid’s surface . This is because some of the liquid will cling onto the surface of the hydrometer stem due to capillary action in a way the makes a curved surface of the liquid. The vertex of this curve is where the reading shall be taken.
What scale is used for hydrometers?
As stated earlier, there are several scales available for hydrometers, most common which is “specific gravity”.
Can you use a hydrometer with multiple scales?
It is possible for some hydrometers to have multiple scales printed on them . You need to fill the hydrometer jar with the sample liquid to use it. Place the device in the jar and quickly twirl it to dislodge any trapped air. You can read from your desired scale one the hydrometer has settled. Note that you need to keep the sample liquid temperature at 60°F to get an accurate measurement. Evidently, you need to adjust the measurement for liquid temperatures other than 60°F.
How does a hydrometer work?
Instead, the hydrometer has a weight at the bottom that's calibrated to a specific level. This hydrometer then sinks or rises depending on the density of the liquid. Lighter liquids will make the hydrometer sink and heavier liquids will make the hydrometer rise.
How to read a hydrometer?
Reading a Hydrometer. To read a hydrometer, you need to look at where your water level is. A specific gravity reading of 1.02. Because the reading is higher than 1.000, this liquid is denser than pure water. Your reading should not be at the top of these waves, but where your liquid is when there are no waves.
What is the difference between a hydrometer and an alcohol hydrometer?
The difference is your alcohol content of your liquid. For example, if you get a reading of 17 percent before fermentation and 2 percent after fermentation, then your alcohol content is 17 - 2 = 15 percent. Alcohol hydrometers are also referred to as alcoholmeters.
Why does a hydrometer scale look backwards?
The scales on hydrometers will look backwards to you if you're used to a thermometer scale. A thermometer scale increases as you go up the tube but a hydrometer's scale increases as you go down the tube. This is because heavier liquids make your hydrometer rise, thus lowering the location where the top part of the liquid reaches.
Why do fish need hydrometers?
Hydrometers can be used to measure the density of saltwater. This is important because marine fish require a specific amount of salt in their water. So fish-keepers who mix their own saltwater must use a hydrometer to make sure that their mixture is just right for their fish.
Where is the weight on a hydrometer?
A weight sits at the bottom, and a scale at the narrow top end. Hydrometers are used in marine fish-keeping, wine-making, and the milk industry. There are different scales depending on the use of the hydrometer. Scale. Description.
What is the tool that measures the density of a liquid?
This little tool is called the hydrometer , which measures the density of a liquid. Hydrometers look a lot like thermometers, except they don't have an internal liquid that rises and falls. Instead the hydrometer has a weight at the bottom that is calibrated to a specific level.
