The gold standard for octane determination of gasoline, the CFR® F1/F2 combines both globally-accepted methods for octane determination in one reconfigurable system. The CFR F1/F2 can be set up for either ASTM® D2699 (IP 237) Standard Test Method for Research Octane Number (RON) or ASTM D2700 (IP 236) Standard Test Method for Motor Octane Number (MON). CFR units are recognized worldwide for producing consistent, accurate test results in determining combustion characteristics of automotive gasolines, aviation gasoline and diesel fuels.
• Combination Unit requires only minor equipment adjustments to switch between Research and Motor Methods
• Variable compression cylinder allows compression ratio to be changed during engine operation and allows wide range of fuel testing
• Durable, simply designed crankcase for easy measurement and repair of key internal components
• Single-venturi carburetor permits easy adjustment of air/fuel ratios
• Factory-calibrated detonation meter (available in 50 or 60 Hz) converts changes in combustion knock to an analog signal; displays knock intensity on a scale of 0 - 100
