The RVP Pro Vapor Pressure Analyzer is engineered for high-precision fuel testing and ensures compliance with ASTM D5191 and ASTM D6378. Designed for laboratories, refineries, and field applications, it offers unmatched accuracy, portability, and durability in vapor pressure analysis.

Engineered for Maximum Performance

RVP Pro significantly outperforms the published precision of all standard test methods, making it the preferred choice for fuel quality control. The Nickel-plated measuring cell and stainless-steel valving technology ensure minimal sample carryover, delivering consistent and repeatable results.This construction provides exceptional resistance to aggressive samples and paraffin/wax fouling, common issues that compromise measurement accuracy in conventional analysers.

The analyzer’s comprehensive sample circuit rinsing system virtually eliminates cross-contamination between tests, ensuring measurement integrity even in high-throughput laboratories. This advantage is particularly crucial when testing samples with significant compositional differences, such as transitioning between gasoline, jet fuel, and crude oil analyses.

For operations requiring regular testing of multiple sample types, the RVP Pro™ delivers consistent results without the time-consuming cleaning procedures. This design philosophy extends to all aspects of the analyzer’s operation, with each component selected and engineered to maximize performance while minimizing maintenance requirements.

Advanced Thermal Management for Consistent Results

Temperature stability is crucial for accurate vapor pressure measurement. RVP Pro incorporates cutting-edge thermal isolation technology, that isolates the heat sink and measuring cell from the mounting plate. This ensures consistent measurement accuracy, even in high-throughput environments.

The temperature control system maintains stability within ±0.01°C (0.02°F) across the full operating range of 0-100°C . This exceptional thermal stability contributes significantly to the analyzer’s ability to outperform the published precision requirements of all supported standard test methods.

Versatile Compliance with International Standards

The RVP Pro supports all major vapor pressure test protocols including ASTM D5188, ASTM D5191, ASTM D6377, ASTM D6378, EN 13016-1, EN 13016-3, GB/T 11059, IP 394, IP 481, JIS K2258-2, SH/T 0769, and SH/T 0794.

The analyser also provides excellent correlation to traditional Reid Vapor Pressure methods (ASTM D323 wet Reid and ASTM D4953 dry Reid), supporting operations transitioning from legacy testing protocols to modern automated analysis.

Beyond standard methods, the RVP Pro offers four user-programmable methods with fully configurable measurement parameters and correlations. This flexibility allows laboratories to develop specialized testing protocols for unique sample types or specific research applications without purchasing additional equipment.

User-Friendly Operation for Skilled and Non-Skilled Personnel

Featuring an 8” industrial-grade capacitive touchscreen, RVP Pro provides an intuitive menu structure for effortless operation. The high-contrast display ensures optimal readability, even when wearing heavy PPE gloves.This interface design facilitates rapid training of new personnel, reducing operational costs and minimizing the risk of procedural errors.

User profiles can be quickly created to allow non-skilled personnel to perform complex measurements with a single button press.

Unmatched Portability for Field Applications

Designed for field applications, RVP Pro comes with a custom Pelican case for secure transport. The transport lock system stabilizes the shaker mechanism, preventing damage during shipping. The ergonomic carrying handle and vibration-dampening high-grip mounting pads provide stability during setup and operation in field environments.

Reliable Performance in Harsh Conditions

Built with industrial-grade components, RVP Pro is engineered for severe-duty use. The chemical-resistant finish protects against aggressive fuel samples, ensuring long-term durability.

Robust Data Management and Connectivity

With USB, RS232, and Ethernet connectivity, RVP Pro enables real-time data transfer to LIMS, printers, and external storage devices. The self-diagnostics system ensures error-free operation, reducing downtime.

Modern laboratory operations require seamless data integration. The RVP Pro™ stores over 50,000 detailed test results in its internal database, with export capabilities in CSV format for easy transfer to Laboratory Information Management Systems (LIMS) or other data analysis platforms.

Connectivity options include 3x USB Type A ports, 1x USB Type B port, RS232, and Ethernet (10/100 Mbit/s compliant with IEEE802.3-2002 standard). These interfaces support connection to barcode readers for sample identification, printers for immediate report generation, and network systems for centralized data management.

The Linux operating system provides superior cybersecurity, protecting valuable test data and ensuring system integrity. Software upgrades can be easily applied without requiring an external PC, reducing IT support requirements and system downtime.

The RVP Pro™ vapor pressure analyzer represents a significant advancement in VAPOR PRESSURE testing. Its combination of precision, durability, usability, and portability makes it the preferred choice across the petroleum industry.

Whether deployed in high-throughput laboratory environments or challenging field conditions, the Koehler RVP Pro™ delivers consistent, accurate results with minimal operator intervention. This performance reliability, coupled with comprehensive standard method support and advanced data management capabilities, provides exceptional value for operations where vapor pressure measurements impact product quality, regulatory compliance, and process efficiency.

The RVP Pro sets the standard for automated vapor pressure analysis.
