Frequently Asked Questions

What is an API hydrometer used for?

An API hydrometer measures the specific gravity of petroleum products and crude oils according to the American Petroleum Institute (API) scale. This plain-form glass instrument is used in refineries, laboratories, and quality-control settings to determine API gravity, which correlates to crude oil density and quality.

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

This API hydrometer has a range of 39/51 API degrees, scale divisions of 0.1, and an overall height of 13 inches. It is made of glass and follows the ASTM Plain Form design. The manufacturer part number is GW005H. It is suitable for precise gravity readings in petroleum testing.

Where to buy API hydrometers worldwide?

3G Electric supplies API hydrometers worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your site. Contact us to order the API ASTM Plain Form hydrometer (MPN GW005H) for reliable sourcing and international shipping.

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 crude oils with API gravity between 39 and 51, the API ASTM Plain Form hydrometer with 0.1 scale divisions is appropriate. Ensure the glass instrument is clean and used at the calibrated temperature for accurate readings.
