Frequently Asked Questions

What is an API hydrometer used for?

An API hydrometer measures the specific gravity of petroleum products according to ASTM standards. It is essential in refineries, fuel blending, and quality control labs to determine API gravity, which indicates crude oil density and helps classify light, medium, or heavy grades.

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

This API hydrometer has a range of 9/21 API, scale divisions of 0.1, and an overall height of 13 inches. It is an ASTM Plain Form instrument, part number GW002H, designed for precise specific gravity measurement of petroleum products in laboratory and field applications.

Where to buy API hydrometers worldwide?

3G Electric supplies API hydrometers worldwide, handling full logistics and customs clearance for global delivery. As a sourcing partner, we provide this API ASTM Plain Form instrument (MPN GW002H) to refineries, testing labs, and industrial facilities across all regions.

How to select the right API hydrometer for petroleum testing?

Select an API hydrometer based on the expected API gravity range of your petroleum product. For light crude, choose a range like 9/21 with fine divisions of 0.1. Ensure the instrument meets ASTM standards and has a suitable overall height for your test jar depth.
