Method : ASTM D5191, ASTM D6377, ASTM D6378, ASTM D5188, ASTM D6897, ASTM D8009. The SetaVap4 is a fully automated vapour pressure analyser which provides fast, reliable and precise analysis of a wide range of volatile liquids, including gasoline, solvents and light crude oil. The measurement system uses a piston based design in compliance with triple and single expansion test methods and regulations, reporting DVPE, RVP, EPA and CARB calculations. For precise results, the minimum dead volume design reduces sample carryover and a fully automated test sequence removes possible operator bias. A colour touch screen and clear user interface guides the operator through the menu system and simple operator sequence. Results are stored internally and can be viewed on the screen or saved directly to a USB memory stick or LIMS for further data management and analysis. • Rapid, automatic testing • Simple test procedure • Compact, rugged design for portable or laboratory use • Real time display of test progress and storage for 500,000 results • LIMS connectivity and RS232C serial port, results can be saved to USB or transferred via QR code • Statistical Quality Control (SQC) software to analyse results to conform to ASTM D6299 • Test multiple temperatures and multiple V/L ratios (ASTM D6377)
