Common Fuel Hydrometers

For users checking the density of different fuels, there are several common hydrometers we provide. These hydrometers will suit standard density ranges, however it's always best to check with our friendly sales staff if a hydrometer recommendation needs to be made. A single hydrometer can be used for 98% high octane fuel, whereas two hydrometers may be required for jet fuels and avgas.

All hydrometers above are manufactured without an inbuilt thermometer. If one is required, we would recommend a -10 to +50 degrees extended length thermometer.
