Product Overview
The Eralytics ERAVAP is a compact, highly precise and easy to use vapour pressure tester, known for unmatched precision, speed and versatility across the widest temperature range available on the market. A small footprint and true portability, even with an attached 10-position autosampler, make it the instrument of choice for both stationary and mobile laboratories.
ERAVAP measures in full compliance with ASTM D5191, ASTM D6377, ASTM D6378, ASTM D6897, ASTM D4052, EN 13016-1, EN 13016-2, EN 13016-3, GOST R 52340, IP 394, IP 409, IP 481, ISO 12185, JIS K2258-2, SH/T 0769, SH/T 0794 and SN/T 2932. ASTM D323, D1267, D2533, D2879, D4953, D5190 and D5482 are supported as correlation methods.
A ground-breaking option is the DENS4052 module: an ultra-light, temperature-controlled X-oscillating metal U-tube density cell that lets a single ERAVAP report vapour pressure and density from the same sample injection, in compliance with ASTM D4052 and ISO 12185.
The California Air Resources Board (CARB) relies on the precision of ERAVAP, as does the U.S. EPA, which uses it as a reference instrument for vapour pressure testing. ERAVAP is also field-proven by the US Army, with close to 100 installations in mobile laboratories worldwide.
