DFA-70Xi
Diesel Fuel Analyzer: Cloud, Pour, Viscosity & Density
State-of-the-Art Solution
Phase Technology’s DFA-70Xi diesel fuel analyzer is the world’s first and only instrument that performs four important tests in one single unit—cloud point, pour point, viscosity and density. And, it does it all in less than 25 minutes!
Product Overview
Phase Technology’s DFA-70Xi diesel fuel analyzer is the world’s first and only instrument that performs four important tests in one single unit—cloud point, pour point, viscosity and density. And, it does it all in less than 25 minutes!
The DFA is also available as a 5-in-1 analyzer, adding freezing point for jet fuel. That makes it the most versatile analyzer in your lab!
The DFA-70Xi features a 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-70Xi 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.
With an unsurpassed precision, DFA-70Xi’s ASTM D5773 cloud point method, ASTM D5949 pour point method, and ASTM D7945 viscosity method are all approved test methods in ASTM’s diesel (D975), biodiesel (D6751) and biodiesel blends (D7467) specifications.
The DFA-70Xi is also available with a 48-station autosampler, which allows unattended testing. Users can initiate 1 to 48 runs in a row, then walk away and let the analyzer do the rest.
