Frequently Asked Questions
What is the measurement range of this hydrometer?
This hydrometer measures specific gravity from 0.800 to 0.950 g/cm³, making it suitable for light oils like diesel, gas oil, and light fuel oil used in marine engines.
How do I use this hydrometer for fuel testing?
Pour a sample of the oil into a clean test cylinder, gently lower the hydrometer and allow it to float freely. Wait for it to stabilize and read the scale at the bottom of the meniscus. For optimal accuracy, perform the test at the calibrated temperature of 15°C (60°F) or apply a temperature correction factor.
Can I use this hydrometer for heavy fuel oil (HFO)?
No, this hydrometer is calibrated for light oils only. For heavy fuel oil with a density above 0.950 g/cm³, you need a hydrometer with a higher measuring range.
Is this hydrometer calibrated to industry standards?
Yes, it is manufactured according to ASTM E100 and ISO 387 standards, ensuring reliable and repeatable results for marine fuel density measurement.
