Frequently Asked Questions

What is an API hydrometer used for?

An API hydrometer measures the specific gravity or density of petroleum liquids and their products. It is commonly used in refineries, fuel testing labs, and storage terminals to determine API gravity, which indicates whether a crude oil is light, medium, or heavy.

What are the specifications of the API Hydrometer GW028H?

The API Hydrometer GW028H has a range of 35/41, scale divisions of 0.1, and an API ASTM Plain Form scale type. Its overall height is 6 3/8 inches. This API-branded instrument is designed for precise density measurement of petroleum liquids.

Where to buy API hydrometers worldwide?

You can source API hydrometers worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the GW028H model.

How to select the right API hydrometer for fuel testing?

Select an API hydrometer by matching its range and scale divisions to the expected API gravity of your fuel. For example, the GW028H covers 35/41 with 0.1 divisions. Always verify the scale type (API ASTM Plain Form) and ensure the instrument is clean and calibrated before use.
