Frequently Asked Questions

What is the API Hydrometer GW073H used for?

The API Hydrometer GW073H is used to measure the specific gravity of petroleum products and liquids in accordance with ASTM standards. It is commonly employed in refineries, laboratories, and quality control settings to determine API gravity, which indicates fuel density and quality.

What are the specifications of the API Hydrometer GW073H?

The API Hydrometer GW073H has a range of 19/31 with scale divisions of 0.1. It features a 30/220ºF mercury thermometer and an API ASTM Combined Form scale type. The overall height is 15 inches. This hydrometer is manufactured by API under part number GW073H.

Where to buy the API Hydrometer GW073H worldwide?

You can source the API Hydrometer GW073H through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply this hydrometer to customers across multiple industries.

How to select the correct API hydrometer for testing?

Select an API hydrometer based on the expected API gravity range of your liquid. For example, the GW073H covers 19/31 with 0.1 divisions, suitable for medium-density petroleum products. Ensure the hydrometer includes a thermometer (here, 30/220ºF) and matches ASTM Combined Form requirements for accurate readings.
