VPV Pro – Confidence Under Pressure

The Grabner VPV Pro is a highly versatile, portable vapor pressure analyzer delivering best-in-class precision across an exceptionally wide pressure range of 0–2000 kPa (290 psi). Engineered for demanding laboratory and field environments, it is the first vapor pressure tester certified for robustness and durability, setting a new benchmark for reliability.

Designed for maximum performance, the VPV Pro accurately measures gasoline, jet fuel, crude oil, LPG, solvents, and more. Proven long-term testing demonstrates outstanding repeatability across the full measuring range. Proprietary 2D-Correction™ technology with exact piston positioning ensures consistent accuracy, while the Sampling Pro™ valve design minimizes cross-contamination—even when switching between diverse sample types.

Certified for operation in extreme climates and resistant to shock and vibration, the Grabner VPV Pro is ideally suited for mobile laboratories, military use, and harsh industrial environments. Every analyzer comes fully configured for all major vapor pressure methods and includes an integrated shaker for crude oil testing.

For low-volatility applications, the VPV Pro low-pressure configuration delivers exceptional sensitivity and precision, supporting direct and extrapolated absolute vapor pressure measurements comparable to ASTM D2879—without sample evacuation. Grabner VPV Pro combines accuracy, durability, and trusted results in one complete vapor pressure solution.
