hydrometer.
A typical instrument is the storage-battery hydrometer, by means of which the specific gravity of the battery liquid can be measured and the condition of the battery determined.
How do you test the specific gravity of a battery?
Hydrometer for Measuring Specific Gravity
Hydrometers (density meters) measure the specific gravity of liquids. Specific gravity is the ratio of the density of the liquid being tested to the density of water. In the case of battery testing, the hydrometer is measuring the specific gravity of the battery’s electrolyte.
Which instrument is used to measure specific gravity in lead acid battery?
hydrometer
Using a hydrometer
A lead acid battery hydrometer is a special type of hydrometer which looks like a syringe with a bulb. Inside the bulb there is a float which is calibrated for measuring the Specific Gravity (SG).
What tool is used to measure the specific gravity of a battery quizlet?
What instrument is used to measure the specific gravity of the electrolyte in a lead-acid battery? A hydrometer.
How do you measure specific gravity?
The best way to measure specific gravity is to weigh a container and record its weight, then weigh the container full of water and full of the liquid of unknown specific gravity. Subtract the weight of the container from each weight and divide the weight of the liquid being measured by the weight of the water.
Which instrument measures specific gravity Mcq?
Hydrometer
An altimeter is an instrument used to measure altitudes in aircraft.
Measuring Instruments MCQ Question 6 Detailed Solution.

| Hydrometer | measures the specific gravity of a liquid. |
How do you measure specific gravity of battery and voltage with load using appropriate instruments?
Normally, the electrolyte for a battery is mixed such that the specific gravity is less than 1.350. Specific gravity is measured with a hydrometer. A simple hydrometer consists of a glass float inside a glass tube, as shown in Figure 1. The hydrometer float is weighted at one end and sealed at both ends.
What is battery hydrometer?
Battery Hydrometers
Hydrometers (density meters) measure the specific gravity of a battery’s electrolyte. Based on the specific gravity, the user can determine the state of charge of the battery. Retaining these hydrometer readings and data over time is recommended by IEEE as part of any Battery Maintenance Program.
What device is used to test the specific gravity of a cell?
A hydrometer is used to measure the specific gravity of the electrolyte solution in each cell. It’s a tool used to measure the density or weight of a liquid compared to the density of an equal amount of water. A lead-acid battery cell is fully charged with a specific gravity of 1.265 at 80° F.
What tool should be used to do a voltage check on a battery without a built in hydrometer?
On sealed batteries which do not have a built-in charge indicator, the status of charge can be determined by checking the battery’s open circuit voltage with a voltmeter.
What is SOC in electric vehicle?
One of the most important information to understand about your electric vehicle is the state of charge. The battery’s state of charge (SOC) refers to how much charge, or energy, is left in the battery. SOC is measured in percent, and it’s the same measurement as a gas tank fuel gauge in a fuel-powered vehicle.
What is Lactometer used for?
Lactometer is a small glass instrument that is used to test the purity of the milk. It works on the principle of specific gravity of milk (Archimede’s Principle).
What is hygrometer used to measure?
hygrometer, instrument used in meteorological science to measure the humidity, or amount of water vapour in the air. Several major types of hygrometers are used to measure humidity.
Which instrument measures specific gravity of milk?
A hydrometer is an instrument used for measuring the relative density of liquids based on the concept of buoyancy. They are typically calibrated and graduated with one or more scales such as specific gravity.
What should the specific gravity of a fully charged battery be?
1.280 to 1.300
The specific gravity of the electrolyte in a fully charged cell should be from 1.280 to 1.300. If it varies more than 10 points above or below these values, adjust it by drawing off some of the electrolyte with a hydrometer and adding water to lower the gravity, or 1.400 acid to raise the gravity.
How do you measure SG without a hydrometer?
If you want to measure the specific gravity without an hydrometer you could measure the mass of a known volume and divide by the mass of an equivalent volume of water since specific gravity is the ratio of the density of a substance to the density of a substance of reference, usually water.
How do you check a car battery with a hydrometer?
Remove the caps from the battery top, squeeze the hydrometer rubber bulb and submerge the tip into the electrolyte. Release the bulb and let some electrolyte to enter the hydrometer container. Check the electrolyte color. You should be able to see through the colorless liquid.
Which test is performed to check the specific gravity of the electrolyte in a lead acid battery?
battery hydrometer
A battery hydrometer is used to read the relative density (specific gravity) of the sulfuric acid in the electrolyte and check the charge of the battery..
Can we use hydrometer to measure density of milk?
Answer: we can by calibrating the hydrometer. Hydrometer used for measuring density of milk is called lactometer.
What is hydrometer specific gravity?
A hydrometer is an instrument used to measure the specific gravity (or relative density) of liquids; that is, the ratio of the density of the liquid to the density of water. A hydrometer is usually made of glass and consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright.
What is float hydrometer?
What is Float? Float tracks your fermentation activity, temperature and SG to brew better beers. This device can be used in your fermenter. With its food grade housing, WiFi connection and an easy to charge battery, brewers use the Float for measuring fermentation activity and temperature.
