Product Description

The  SX Series Portable Octane and Cetane Meters are advanced handheld analyzers designed for fuel and oil quality testing. These instruments provide fast, accurate, and non-destructive analysis of gasoline, diesel, biodiesel, and lubricants.

Built on high-precision microprocessor technology, the SX series allows real-time quality evaluation in the field or laboratory. Each model supports octane (ASTM D 2699/2700) and cetane (ASTM D 4737/D 613/EN ISO 5165) measurement, with additional capabilities depending on the model.

Compact, durable, and PC-connectable via USB, the SX series is trusted worldwide by oil companies, refineries, laboratories, and quality control teams.

Key Features (All Models)

  • Measures octane number (ON) of gasoline and cetane number (CN) of diesel fuels

  • Compliance with international standards (ASTM, EN ISO)

  • Quick measurement time: 1–5 seconds

  • Built-in memory and USB export (.xlsx / .txt)

  • 8-key anti-glare keyboard, wear-resistant and chemical-proof

  • Portable and field-ready, with ≥6 years useful life
