Hydrometers are used to detect the density of liquids. There are two types of hydrometers: temperature and specific gravity. A hydrometer is a device for measuring the relative density or specific gravity, which describes how dense or heavy a liquid substance is compared to water..
A hydrometer is a device used to measure the specific gravity of liquids. It’s usually used in brewing, winemaking and distilling. The “How do you use a hydrometer for coolant?” is a question that I received from my readership.
Use an antifreeze hydrometer to determine the amount of antifreeze in the system. Suck coolant from the header tank; if a float is present, take a reading at the point when the float breaches the liquid surface and convert to antifreeze strength on the hydrometer chart. If there are balls, the floating numbers and colors indicate the strength; read the directions carefully.
So, what exactly is an antifreeze hydrometer?
With this antifreeze hydrometer, you can accurately test the antifreeze in any car. The hydrometer measures the temperature of ethylene glycol on a scale of -51°C to 0°C (-60°F to 32°F), showing if the solution is appropriately mixed to avoid freezing.
Also, what is the purpose of a coolant refractometer? Machine tool coolants, heat treatment fluids, hydraulic fluids, plating baths, detergents, antifreeze, battery acid, and other water soluble fluids are measured using refractometers, which are handheld, lightweight, portable equipment.
Similarly, what temperature should antifreeze be tested at?
Starting with a cold engine is the best way to go. Start the engine after removing the radiator cap. Set your digital multimeter to DC volts at 20 volts or less on your digital multimeter. Insert the positive probe straight into the coolant after the engine has reached operating temperature.
What is the name of the antifreeze tester?
Prestone Antifreeze/Coolant Tester is a professional do-it-yourself tester for antifreeze/anti-boil protection that is simple to use. It also enables you to examine the antifreeze as it is being tested. This is a low-cost method of checking the antifreeze/coolant level in your car.

What is the purpose of a hydrometer?
A hydrometer is a device that measures the specific gravity or relative density of liquids, which is defined as the ratio of the liquid’s density to that of water. A hydrometer cylinder is filled with the liquid to be tested, and the hydrometer is gradually dropped into the liquid until it floats freely.
Antifreeze testers: how reliable are they?
Review of the 4293 Laser Ethylene Glycol Antifreeze Tester
We also discovered that the findings were similar, with low accuracy and readings approximately nine degrees off for 33 percent concentration anti-freeze, but improved results for 50 percent concentration.
Is antifreeze tested at AutoZone?
For the right tools and testers, relying on AutoZone is a no-brainer. Antifreeze tests, radiator flush kits, and anything else you can think of are all available from us. Additionally, if you need a tool but do not want to purchase it, consider our Loan-A-Tool service.
How do you check for antifreeze made of propylene glycol?
How to Test Ethylene & Propylene Glycol
- To test a sample of ethylene or propylene glycol-based coolants, use CoolTrak coolant test strips (kimdon.com). To determine the boiling point, freezing point, and pH, dip the strip into the test material.
- Using a refractometer will improve accuracy.
What does Brix mean?
The quantity of grams of sucrose contained per 100 grams of liquid is given as degrees Brix (°Bx). On a scale of one to one hundred, the value is multiplied by 0.59 to provide an estimate of the possible alcohol concentration.
What is the name of the test that compares water and coolant density?
The liquid to be tested is put into a tall container, such as a graduated cylinder, and the hydrometer is slowly lowered until it floats freely. The relative density is determined by the point at which the liquid’s surface hits the hydrometer’s stem.
How can you determine the amount of glycol in your body?
Answer: We have two different types of refractometers that you can use to measure glycol concentration in water. The first is the MISCO 7084VP+ Glycol & Battery Tester. It is a traditional analog refractometer with scales for measuring both ethylene glycol (EG) and propylene glycol (PG) freeze points.
How can you determine the specific gravity of a coolant?
How to determine the coolant’s specific gravity
- Run the engine until it reaches a temperature where the thermostat can be opened.
- Turn off the engine.
- Allow the engine to cool until the coolant temperature falls below 140 degrees Fahrenheit (60 degrees Celsius).
- Remove the cooling system’s filler cap.
- Coolant from the cooling system should be drained into an appropriate container.
What method is used to determine the freezing point of the coolant in a cooling system?
Antifreeze strength is measured using two devices: an antifreeze hydrometer and a refractometer. The antifreeze hydrometer is used to determine the cooling system’s freezing point. Coolant is drawn into the tester by a press and release bulb, and a needle floats to represent the freeze protection point.
What is the specific gravity of a coolant?
Hydrometers only function with coolants and antifreeze that contain Ethylene Glycol. Propylene Glycol cannot be measured with a hydrometer because its specific gravity rises up to 70% concentration, but drops over 70% concentration. A 100% solution reads the same as a 40% solution.
What is the refractometer factor, and what does it mean?
How to Use a Refractometer to Determine Concentration (Tech Tip). Furthermore, since each coolant refracts light differently, it has its own unique multiplier, known as a refractometer factor. The coolant concentration may be calculated by multiplying the °Brix measurement by the refractometer factor for the coolant.
What is a glycol refractometer and how does it work?
A refractometer is a device that is used to determine the concentration of a certain chemical in a solution. The concept of refraction is used to operate it. When light rays move through one medium and into another, they are bent toward or away from a normal line connecting the two.
What are the four fluids that a refractometer can test?
Machine tool coolants, heat treatment fluids, hydraulic fluids, plating baths, detergents, antifreeze, battery acid, and other water soluble fluids are measured using refractometers, which are handheld, lightweight, portable equipment.
What is the ratio of coolant to water?
Water and antifreeze should be mixed at a 60:40 to 50:50 ratio. At temperatures ranging from –25°C to –40°C, this generally equates to antifreeze protection. The minimum and maximum mixing ratios should be 70:30 and 40:60, respectively. Increasing the antifreeze mix (for example, 30:70) has no effect on the freezing point.
What is the refractometer’s principle?
Refractometers are devices that are used to determine the concentration of compounds dissolved in water and some oils. The concept of light refraction via liquids is used to operate the refractometer. Light slows down when it travels from air to liquid. This is what gives things that are partly immersed in water a “bent” appearance.
What are the functions of refractometers?
A refractometer is a device used in laboratory medicine to determine the total plasma protein in a blood sample and the urine specific gravity in a urine sample. The refractometer is used to identify gem materials by measuring their refractive index, which is one of the most important qualities in detecting a gemstone’s nature.
What is the purpose of the refractometer?
Refraction occurs when light penetrates a liquid and alters its direction. The angle of refraction, which is measured by refractometers, is the degree to which light changes direction. The refraction angles are measured using a refractometer, which connects them to refractive index (nD) values.
