Frequently Asked Questions

What is an API hydrometer used for?

An API hydrometer measures the specific gravity of petroleum liquids relative to water, as defined by the American Petroleum Institute (API) scale. It is essential in oil refineries, fuel blending, and quality-control labs for classifying crude oil and refined products.

What are the specifications of the API Hydrometer GW2508?

The API Hydrometer GW2508 has an API Plain Form scale with a range of 69/81 and scale divisions of 0.2. Its overall height is 6 inches. This hydrometer is designed for precise density measurement of petroleum products and complies with API standard specifications.

Where to buy API Hydrometer GW2508 worldwide?

You can source the API Hydrometer GW2508 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time.

How to select the right API hydrometer for petroleum testing?

Select an API hydrometer based on the expected API gravity range of your petroleum sample. The GW2508 covers 69/81 with 0.2 divisions, suitable for light hydrocarbons. Ensure the hydrometer is clean, at the correct temperature, and used per ASTM D1298 for accurate readings.
