API Hydrometers – Measuring the Density of Crude Oil and Petroleum<\/h1><\/div>

Our API hydrometers<\/strong> enable the exact determination of the density of crude oil and petroleum products in laboratories, refineries and industrial applications. The API gravity scale describes the specific gravity of crude oil and allows different oil qualities to be assessed in a standardised way. A high-quality API hydrometer delivers reliable, reproducible readings of the API gravity.<\/p>\n<\/div>

API hydrometers built to ASTM standards<\/h2>\n<\/div>

Our hydrometers are manufactured to ASTM E100-19 and ASTM E2995-15a and meet international requirements for measuring the density of petroleum. The measuring range of \u22121 to +101 \u00b0API allows even small density differences to be captured precisely, at a resolution of 0.1 \u00b0API. The reference temperature of 60 \u00b0F keeps the measured values compliant with the standard and directly comparable.<\/p>\n<\/div>

Versions for different requirements<\/h2>\n<\/div>

Our API hydrometers come in several versions, either with an integrated thermometer<\/strong> or as a pure density instrument<\/strong>. Models with an integrated thermometer allow direct temperature monitoring during the measurement, which is particularly useful when determining the specific gravity of crude oil under variable conditions.<\/p>\n<\/div>

Accessories and practical use<\/h2>\n<\/div>

For the use of API hydrometers<\/strong>, suitable cylindrical glass stands are available as accessories. They keep the hydrometer stable and upright during the measurement and contribute significantly to accurate results. Combined with a high-quality API hydrometer, they enable reliable determination of both the density of petroleum<\/strong> and the corresponding API gravity<\/strong>.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

API hydrometers with calibrated quality<\/h2>\n

If you need a reliable API hydrometer for professional applications, we offer precise, durable instruments. On request, your measuring instruments come with a works calibration certificate or a traceable DAkkS calibration certificate, so all readings remain documented and traceable over the long term.<\/p>\n<\/div>
