Frequently Asked Questions

What is the API Hydrometer GW055HM used for?

The API Hydrometer GW055HM 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 GW055HM?

The API Hydrometer GW055HM has a range of 39/51 with scale divisions of 0.1. It features a +30 / 180ºF Mercury Thermometer and an overall height of 15 inches. The scale type is API ASTM Combined Form, and the manufacturer part number is GW055HM.

Where to buy the API Hydrometer GW055HM worldwide?

You can source the API Hydrometer GW055HM 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 procurement teams internationally.

How to select the correct API hydrometer for petroleum testing?

Select an API hydrometer based on the expected API gravity range of your petroleum sample. The GW055HM covers 39/51 with 0.1 divisions, suitable for medium to heavy crude. Ensure the hydrometer includes a thermometer for temperature correction, as API gravity is temperature-dependent. Always verify ASTM compliance for your test method.
