PSSC RVP Pro — Automated Vapor Pressure Analysis for Petroleum, Fuel & Crude Oil
ASTM D5191 · D5188 · D6377 · D6378 compliant. ISO 17025 accredited calibration with standard delivery. One-button operation. Built for high-volume labs and field use.
ISO 17025 accredited calibration with standard delivery
Vapor pressure is one of the most tightly regulated physical properties in petroleum and fuel quality programs — and one of the most vulnerable to operator error when run manually. Incorrect results don’t just fail an audit; they affect blending decisions, product release, and EPA compliance.
The PSSC RVP Pro is a fully automated vapor pressure analyzer built for petroleum, fuel, crude oil, gasoline, jet fuel, and solvent testing. It performs in 5 minutes per sample, requires just 1 mL of sample, and outperforms the published precision of every ASTM method it supports — run after run, operator after operator.
What the RVP Pro Delivers in Your Lab
One-Button Operation
Single user profile creation means non-skilled personnel produce consistent, compliant results every time — no training overhead, no method variation.
5-Minute Run Time
Designed for high-throughput environments. Full automated vapor pressure measurement without sacrificing precision — significantly faster than manual methods.
Virtually Zero Carryover
Industry-proven nickel-plated measuring cell with stainless-steel valving fully rinses the entire sample circuit between runs — nearly eliminating cross-contamination.
Field & Lab Ready
Ergonomic Pelican case, transport lock, and vibration-dampening pads. The only vapor pressure analyzer built for tank farms, rail loading racks, pipelines, and mobile labs.
50,000+ Result Storage
CSV, RTF, and XML export with full LIMS integration. No external PC ever required — Linux OS with onboard storage and direct network connectivity.
ISO 17025 Calibration Certificate Included
Every RVP Pro ships with an ISO/IEC 17025:2017 accredited calibration certificate as standard — not as a paid add-on. Ready for audit from day one.
ASTM Method Compliance
Total Vapor Pressure of Petroleum Products & Fuels — Mini Method
The primary automated RVP method for gasoline and fuel blends. Required for EPA CFR Part 1040 compliance. Replaces manual D4953 with a 1 mL sample and 5-minute run time.
Vapor Pressure of Crude Oil — VPCRx Expansion Method
The industry standard for crude oil custody transfer and product release decisions. Adjustable V/L ratio from 0.02:1 to 4:1 covers full crude oil testing range.
Vapor Pressure — Triple Expansion Method
Used for precise blending compliance across refined petroleum products and hydrocarbon mixtures. Delivers the highest precision of the triple-expansion methods.
Vapor-Liquid Ratio — Fuel Vapor Lock Temperature
Determines the temperature at which a fuel-air mixture causes vapor lock. Critical for fuel performance evaluations and handling safety assessments.

Frequently Asked
Questions
Answers to what laboratory managers, QC teams, and procurement professionals ask most often about the PSSC RVP Pro.
What does the PSSC RVP Pro measure?
The RVP Pro measures the vapor pressure of petroleum products including crude oil, gasoline, jet fuel, and solvents. It performs automated vapor pressure analysis per ASTM D5191, D6377, D6378, and D5188, producing results in approximately 5 minutes per sample with just 1 mL of sample required.
What ASTM methods does the RVP Pro support?
The RVP Pro is compliant with ASTM D5188, D5191, D6377, and D6378. It also correlates to ASTM D323 (wet Reid) and D4953 (dry Reid), and meets international standards including EN 13016-1, EN 13016-3, IP 394, and IP 481. Four additional user-programmable methods are also available.
How does the RVP Pro compare to manual Reid vapor pressure methods?
Manual methods like ASTM D323 require lengthy bath setup, careful sample handling, and approximately 30 minutes per test. The RVP Pro automates the entire process — 1 mL of sample, 5-minute run time, one-button operation — with precision that outperforms all published manual method tolerances.
Is the RVP Pro suitable for field use, or is it laboratory only?
The RVP Pro is designed for both. It ships with a custom-fit Pelican case, a transport lock to protect the shaker system during transit, and vibration-dampening pads — making it suitable for tank farms, pipeline terminals, truck and rail loading racks, and mobile laboratory applications.
Does the RVP Pro come with calibration?
Yes. Every RVP Pro ships with an ISO/IEC 17025:2017 accredited calibration certificate as standard — not as a paid add-on. PSSC also offers ongoing 6-month ASTM calibrations including performance verification with certified reference materials.
What industries use vapor pressure analyzers like the RVP Pro?
The RVP Pro is used in petroleum refinery QC labs, fuel pipeline and terminal operations, independent petroleum testing labs, government and military labs, lubricant manufacturers, and university research departments — anywhere that ASTM D5191, D6377, or D6378 compliance is required.
