- A hydrometer is an instrument that measures the specific gravity (relative density) of liquids the ratio of the density of the liquid to the density of water.
- Material: Glass, Color: Clear, Hydrometer for Measuring Unleaded Petrol - Measurement Range- (0.750 to 0.800)
- The hydrometer used for taking specific gravity readings .The most accurate way to determine an object's volume, especially in the case of an irregularly shaped object, is to immerse it in water and measure the amount of water it displaces.
- The point at which the surface of the liquid touches the stem of the hydrometer correlates to specific gravity.
- Comes with a protector case.
