Density Meters

Also known as hydrometers, these measure the density of a liquid compared to the density of water. Pour your liquid into a tall container and immerse the density meter into the liquid until it floats. Take the reading where the surface of the liquid touches the scale on the meter. Heavy liquids sink in water and light liquids float in water.

Meter with
1.1 to 1.35
Specific Gravity Range

Check the condition of battery fluid by measuring its density to indicate the state of charge.

Meter with built-in thermometer compensates for temperature variations for more accurate readings.

Meter with specific gravity range of 1.1 to 1.35 can withstand drops as high as 10 feet.

Concentration Meters

Also known as refractometers, these measure concentration with two or three drops of a solution. Place your sample on the reflecting prism and look through the eyepiece to view the concentration on the internal scale.

Concentration meters with automatic temperature compensation standardize readings at 68° F to prevent inaccurate results in fluctuating temperatures.

Concentration meters with freezing-point scale measure the freezing point of propylene glycol and ethylene glycol as well as the specific gravities of battery acids from 1.15 to 1.30.
