Shatox Portable Gasoline Octane Number and Diesel Cetane Number Analyzer

Overview

The Shatox Portable Gasoline Octane Number and Diesel Cetane Number Analyzer is a field-deployable, dual-parameter fuel quality assessment instrument engineered for rapid, on-site determination of gasoline octane number (ON) and diesel cetane number (CN). Unlike traditional ASTM D2699/D2700 (RON/MON) or ASTM D613 (cetane number) laboratory methods—which require large-scale engine-based testing—the Shatox system employs a proprietary electromagnetic induction and electro-osmotic response analysis principle. This non-destructive, solvent-free methodology detects characteristic dielectric and conductive perturbations in hydrocarbon fuels induced by applied low-frequency electromagnetic fields. The resulting signal profiles are correlated to reference calibration datasets traceable to primary standard fuels certified by national metrology institutes. Designed for operational continuity across logistics hubs, refineries, fuel depots, and roadside inspection units, the analyzer delivers laboratory-grade repeatability under variable ambient conditions—without requiring sample dilution, combustion, or consumables.

Key Features

• Simultaneous ON and CN quantification in a single 1–5 second measurement cycle
• Integrated temperature sensor and diesel cloud point estimator with real-time LCD display
• Ruggedized portable enclosure compliant with IP54 environmental rating for dust and splash resistance
• Onboard memory storing up to 500 test records with timestamp, GPS coordinates (optional module), and operator ID
• Calibration traceability via RS-232 interface to Windows Mobile-based Pocket PC platforms (Microsoft Pocket PC 2000/2002 compatible)
• Self-diagnostic firmware with automatic zero-point verification and sensor drift compensation
• Battery-powered operation (rechargeable Li-ion, >8 hours continuous use) enabling true offline deployment

Sample Compatibility & Compliance

The Shatox analyzer is validated for direct analysis of undiluted, commercially available gasoline (including ethanol-blended E10/E15), reformulated gasoline (RFG), and middle-distillate diesel fuels (EN 590, ASTM D975, GOST R 52368). It excludes heavy fuel oils, biodiesel blends exceeding B7, or fuels containing metallic additives (e.g., Mn-based antiknock agents) due to interference with electromagnetic response signatures. While not a replacement for regulatory engine-test methods per ASTM D2699, D2700, or D613, the instrument meets the performance criteria outlined in ASTM D7762 (“Standard Practice for Field Screening of Fuel Quality Using Portable Analyzers”) and supports ISO 8217 Annex A verification workflows. Data integrity complies with GLP audit requirements through embedded electronic logbooks and configurable user access levels.

Software & Data Management

Instrument configuration, calibration updates, and data export are managed via the Shatox PC Utility Suite—a Windows-compatible application supporting CSV and XML export formats. All measurement sessions include mandatory metadata capture: ambient temperature, fuel temperature, operator credentials, and device serial number. Audit trails conform to FDA 21 CFR Part 11 principles where electronic signatures and immutable record retention are configured. Firmware versioning follows IEC 62443-3-3 cybersecurity guidelines; no internet connectivity is required during operation, minimizing attack surface exposure.

Applications

• Real-time verification of gasoline octane compliance at refinery offloading points and retail terminals
• Field screening of diesel fuel cetane adequacy prior to engine commissioning or fleet refueling
• Forensic fuel adulteration detection (e.g., kerosene dilution in diesel, leaded gasoline substitution)
• Quality assurance during fuel transportation and storage—especially in remote or infrastructure-limited regions
• Supporting ISO/IEC 17025-accredited laboratories for preliminary triage before confirmatory engine testing
• Training and education in petroleum engineering curricula focusing on empirical fuel property correlation

FAQ

Does the Shatox analyzer replace ASTM D2699/D2700 or D613 testing?
No—it serves as a rapid screening tool aligned with ASTM D7762. Regulatory submissions and certification require primary engine-based methods.
Can it measure oxygenated gasoline blends such as E85?
It is validated for E0–E15; E85 and higher ethanol concentrations fall outside its calibrated range due to dielectric saturation effects.
Is third-party calibration certification available?
Yes—traceable calibration certificates issued by accredited Russian NMIs (e.g., VNIIM) are provided with each unit shipment.
What maintenance is required?
Annual sensor validation using certified reference fuels; no routine consumables or fluid replacements are needed.
How is temperature compensation handled during field measurements?
Dual-sensor thermal profiling (ambient + fuel) feeds into real-time algorithmic correction of ON/CN outputs per ISO 4213 interpolation protocols.
