Frequently Asked Questions

What is an API ASTM Combined Form hydrometer used for?

An API ASTM Combined Form hydrometer measures the specific gravity of petroleum products and crude oils. It is used in refineries, laboratories, and quality control to determine API gravity, which correlates to fuel density and quality. The built-in mercury thermometer allows simultaneous temperature measurement.

What are the specifications of the API Hydrometer GW051HH?

The API Hydrometer GW051HH has a range of -1/11 API, scale divisions of 0.1, and an overall height of 15 inches. It features a +60 / 220ºF mercury thermometer and is an API ASTM Combined Form scale type. This model is manufactured by API Instruments.

Where to buy an API Hydrometer GW051HH worldwide?

3G Electric supplies the API Hydrometer GW051HH to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your location. Contact us for pricing and lead time on this precision instrument.

How to select the right API hydrometer for crude oil testing?

Select an API hydrometer based on the expected API gravity range of your crude oil. The GW051HH covers -1/11 API, suitable for heavy to medium crudes. Ensure the scale type (ASTM Combined Form) matches your test method. Always verify the thermometer range covers your sample temperature.
