Model 1140 Micro-Separometer

For quality control purposes, water separation characteristics of fuels are rated to determine the amount of surface active materials (surfactants) present. 

Surfactants degrade the performance of filter separators used to remove water from the fuel. The presence of water can impair engine performance and initiate microbiological growth, which can cause corrosion in tanks and filter plugging in fuel lines. 

Also for quality control purposes, fuels are subjected to “Clear & Bright” tests to determine the amount of free water and particulate matter in mid-distillates.

The Model 1140 Micro-Separometer is a electro-mechanical instrument used to perform four discrete tests. 

ASTM Standard Test Methods D3948 (Jet), D7224 (Jet) and D7261 (Diesel) are used to rate water separation characteristics and D4860 (Jet or Diesel) detects and numerically rates free water and particulate contamination.  

This instrument performs each of the four tests above simply by using one of the four “Six Packs” containing the proper coalescer cells.
