Product Description

The API Hydrometer is an API ASTM Plain Form instrument with a range of 15/21 and scale divisions of 0.1. This hydrometer, manufactured by API under part number GW024H, has an overall height of 6 3/8 inches and is designed for measuring the specific gravity of petroleum products.

Frequently Asked Questions

What is an API hydrometer used for?

An API hydrometer measures the specific gravity of petroleum products and crude oils. It is essential in refineries, fuel testing labs, and quality control for determining API gravity, which indicates fuel density and quality.

What are the specifications of the API ASTM Plain Form hydrometer?

This API hydrometer has a range of 15/21, scale divisions of 0.1, and an overall height of 6 3/8 inches. It is an API ASTM Plain Form instrument, part number GW024H, designed for precise petroleum product density measurement.

Where to buy API hydrometers worldwide?

3G Electric supplies API hydrometers worldwide, handling full logistics and customs clearance. As a global industrial solutions provider, we source and deliver genuine instruments like the GW024H to refineries and labs across all regions.

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. For light crude or fuels, a range like 15/21 with 0.1 divisions provides accurate readings. Always verify the ASTM standard and overall height for your test method.
