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 used in refineries, fuel testing labs, and storage terminals to determine crude oil and fuel density for quality control and custody transfer.

What are the specifications of the API ASTM Plain Form hydrometer GW001H?

The API ASTM Plain Form hydrometer (MPN GW001H) has a range of -1/11 API, scale divisions of 0.1, and a 13-inch overall height. It is designed for precise density measurement of petroleum products per ASTM standards. The scale type is API ASTM Plain Form.

Where to buy API hydrometers worldwide?

3G Electric supplies API hydrometers worldwide, including the ASTM Plain Form model GW001H. We handle full logistics, customs clearance, and delivery to your site. Contact our team for a quote and lead time. We source and deliver globally.

How to select the right API hydrometer for petroleum testing?

Select an API hydrometer based on the expected density range of your petroleum product. For light crude or gasoline, a range like -1/11 API with 0.1 divisions (as in the GW001H) is typical. Ensure the hydrometer meets ASTM standards and has a 13-inch length for proper immersion in the test cylinder.

Used in
