Product Description

The API Hydrometer (SKU GW6003, MPN GW6003) is an API Combined Form hydrometer with a 20/40 range and 0.2 scale divisions, made of glass with a 15-inch overall height. It features a 0 to 150ºF thermometer. This instrument is designed for measuring the specific gravity of petroleum products according to API standards.

Frequently Asked Questions

What is an API Hydrometer used for?

An API hydrometer measures the specific gravity of petroleum products according to API standards. It is used in refineries, laboratories, and fuel storage facilities to determine the density of crude oil, gasoline, diesel, and lubricants. The built-in 0 to 150ºF thermometer allows simultaneous temperature compensation for accurate readings.

What are the specifications of the API Hydrometer GW6003?

The API Hydrometer GW6003 has a 20/40 range with 0.2 scale divisions and an API Combined Form scale type. It is made of glass with a 15-inch overall height and includes a 0 to 150ºF thermometer. The manufacturer part number is GW6003, and it is designed for petroleum product density testing per API standards.

Where to buy API Hydrometer GW6003 worldwide?

Contact us for availability and lead time. We source and deliver this instrument to refineries, labs, and industrial facilities globally.

How to use an API Hydrometer for petroleum testing?

To use an API hydrometer, pour the petroleum sample into a clean cylinder, gently lower the hydrometer, and allow it to float freely. Read the scale at the liquid meniscus while noting the thermometer reading. Apply temperature correction per API tables for accurate specific gravity. Always handle glass instruments carefully to avoid breakage.
