DFA 70Xi

Cloud Point , Pour Point , Viscosity & Density Analyzer Cloud point , Pour point , Viscosity , Density analyzer

Phase Technology’s new DFA-70Xi analyzer is the world’s first and only instrument that performs four important diesel fuel tests in one single unit—cloud point, pour point, viscosity and density. And, it does it all in less than 25 minutes! The DFA-70Xi features a new, side loaded automatic sample injection port. There’s no longer a need to manually pipette. The analyzer always draws the precise amount of sample as required by the ASTM method.

The DFA is completely self-cleaning, without the need of solvents. Save time and hassle of cleaning, and avoid any risk of damage to the sample cup.

Methods

Cloud Point – ASTM D5773

Pour Point – ASTM D5949

Viscosity – ASTM D7945

Density – ASTM D4052

Benefits

  • Super fast speed
  • Automatic sample input
  • Self cleaning – no solvent required
  • No manual set-up
  • Superior precision
  • Greater sensitivity

Applications

Diesel and biodiesel fuel’s cold-weather operability and fuel handling characteristics are measured by testing cloud point and pour point. Viscosity is an important parameter to ensure there is proper lubrication, with no damage in the engine’s fuel pump. Viscosity also influences the spray pattern when the fuel is injected into the cylinder. Density affects the heating value (or energy content) of the fuel.
