Practical design for the everyday user

ERAVAP is the ultimate solution among RVP products. This versatile instrument allows for the vapor pressure testing of fuels, solvents, fragrances, or aqueous solutions. With excellent precision, ERAVAP is the preferred analyzer for volatility specification compliance testing, refining streams quality follow-up, fuel blending and research or mobile applications.

ERAVAP is a compact, highly precise, user-friendly vapor pressure tester. It’s portable even with an attached 10 port autosampler, and its rugged aluminum casing makes it the ultimate choice for both stationary and mobile laboratories.

Ideal for R&D and QC measurements, the instrument is fully compliant with the latest standards such as ASTM D5188, D5191, D6378, EN 13016, and many more using a single analyzer.

The instrument’s precision, speed, and versatility provide an unmatched basis for vapor pressure measurement in the oil and gas industry.

*To to improve measurement procedures to maximize safety in crude oil transportation, ERAVAP manufacturer Eralytics closely cooperates with Canadian Crude Quality Technical Association (CCQTA) and the American Crude Oil Quality Association (COQA), a partnership that resulted in the development of a device capable of measuring crude oil at a V/L ratio as low as 0.02/1.
