WSI Analyser

Part Number SA9000-0

The Water Separation Instrument is a fully automatic and compact bench top / portable instrument. The instrument measures how effectively a fuel sample releases entrained and emulsified water when pumped through a water coalescing filter. The WSI displays the measured water separation index. Results can range from 0.0 to 100.0. A high water separation index, such as 100.0, indicates the test specimen coalesces easily and is relatively free of surfactants.

The WSI is operated via a touchscreen user interface that takes you through the testing procedure. The instrument consists of a sonicator, temperature probe, filter cartridge, dye detector and dyed water, solvent and test specimen pumps.
