Frequently Asked Questions

What is an API hydrometer used for?

An API hydrometer measures the specific gravity of petroleum liquids relative to water, using the American Petroleum Institute (API) gravity scale. It is essential in oil refineries, fuel blending, and quality control labs to classify crude oil and ensure product consistency.

What are the specifications of the API ASTM Plain Form hydrometer?

This API ASTM Plain Form hydrometer has a range of 37/49 API gravity, scale divisions of 0.1, and is made of glass with an overall height of 13 inches. The manufacturer part number is GW011H. It is designed for precise density measurement of petroleum products.

Where to buy API hydrometers worldwide?

You can source API hydrometers worldwide through 3G Electric, a global industrial equipment distributor since 1990. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the API ASTM Plain Form hydrometer (MPN GW011H).

How to select the right API hydrometer for petroleum testing?

Select an API hydrometer based on the expected gravity range of your petroleum sample. For light crude or refined products, a range of 37/49 with 0.1 divisions, like the API ASTM Plain Form model, provides adequate resolution. Always verify the scale type matches ASTM standards for accurate results.
