Frequently Asked Questions

What is the API Hydrometer GW057HL used for?

The API Hydrometer GW057HL is used to measure the specific gravity of petroleum products and crude oils per ASTM standards. Its combined form scale and 0/150°F mercury thermometer make it suitable for field and lab testing in refineries, pipelines, and quality control labs.

What are the specifications of the API Hydrometer GW057HL?

The API Hydrometer GW057HL has a range of 59/71, scale divisions of 0.1, and an API ASTM Combined Form scale type. It includes a 0/150°F mercury thermometer and has an overall height of 15 inches. The manufacturer part number is GW057HL.

Where to buy the API Hydrometer GW057HL worldwide?

You can source the API Hydrometer GW057HL 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.

How to select the correct API hydrometer for ASTM testing?

Select an API hydrometer by matching its range and scale divisions to your test method. For ASTM D287, the combined form scale (like the GW057HL with 59/71 range and 0.1 divisions) is standard. Ensure the thermometer range covers your expected sample temperature, such as the 0/150°F mercury thermometer included.
