Description |
Petroleometer No. 481, 725-775 which is used to measure the specific gravity (relative density) of pump gasoline. This is an important indicator of the quality and composition of the fuel. This model is calibrated from 725-775. That means it can measure liquids 72.5-77.5% the density of water. To use it, a small amount of gasoline is added to the bulb and the petroleometer is then placed in the liquid. The marking on the device at the surface of the gas indicates the relative density. It is a brass instrument consisting of a tube which is weighted on the bottom. A five centimetre sphere is five centimetres above the weight. The tube is calibrated from 725 to 775 above the sphere protruding 14 centimetres. It is in a custom wood box with a black molded insert to hold the instrument. A label on the top of the box reads: No. 481, Petroleometer, 725-775, L. Oertling, London. The box has two hook closures on the front. A certification sticker on the bottom reads No. 481, 725-775, Correct, Oct. 25/11, CEW. |
