Product Description

The API Hydrometer, model GW056HL, is an API ASTM Combined Form hydrometer with a range of 49/61 and scale divisions of 0.1. It features a 0/150ºF mercury thermometer and has an overall height of 15 inches. This instrument is designed for measuring the specific gravity of petroleum products according to ASTM standards.

Frequently Asked Questions

What is an API hydrometer used for?

An API hydrometer measures the specific gravity of petroleum products according to ASTM standards. The API ASTM Combined Form model GW056HL is used in refineries and labs to determine API gravity, which indicates crude oil density and quality for processing and trading.

What are the specifications of the API hydrometer GW056HL?

The API hydrometer GW056HL has a range of 49/61 API, scale divisions of 0.1, and an overall height of 15 inches. It features a 0/150ºF mercury thermometer and is an API ASTM Combined Form scale type, designed for precise petroleum gravity measurement.

Where to buy an API hydrometer worldwide?

3G Electric supplies the API hydrometer GW056HL worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to deliver this ASTM-compliant instrument to your facility, ensuring you receive the correct API gravity measurement tool for your application.

How to select the right API hydrometer for petroleum testing?

Select an API hydrometer based on the expected API gravity range of your petroleum product. The GW056HL covers 49/61 API with 0.1 divisions, suitable for light to medium crude. Ensure the hydrometer includes a mercury thermometer (0/150ºF) for temperature correction per ASTM methods.
