Shell Water Detector Kit
Model:W34876
The Problem Water can occur in jet fuel in three forms dissolved (chemically in solution in the jet fuel), settled (as in free water al the bottom of the tank), or as finely dispersed undissolved water held in suspension. It is this undissolved water that the Shell® Water Detector is designed to detect, and it has proven to be reliable for 30 year? This is water that a filter separator can remove and is usually invisible in the eye in quantities below 40-60 ppm.

What It Does


Detects the presence of finely dispersed undissolved water in jet fuels.
Works at free water concentrations below those which can be seen by the human eye.

What It Consists of


A plastic defector capsule in which is fitted a disc of filter paper treated with water sensitive chemicals.
A graduated plastic: syringe and special connector for the capsule the syringe must be ordered separately.

How to Use it


Take a capsule from the tube and check that it is a uniform yellow Color Do not touch or breathe on the paper surface of the capsule.
Push the syringe plunger fully in, then fit the capsule to the Syringe and immerse the capsule and part of the syringe in the fuel.
Draw the plunger back steadily until the fuel in the syringe reaches the 5 ml mark
Examine the capsule for difference of color between the inner wetted center ring and the outer rim.

How to Interpret Results


The presence of free water in fine suspension in the fuel is indicated by a change in color on the center of the capsule.
The chemicals begin to react at the very low concentrations of water contamination. even below 10 ppm. The color changes become progressively more noticeable with increasing water Concentrations until. at approximately 30 ppm, with a 5 ml sample, a strong, obvious green color is obtained - giving a positive indication of the presence of free water.
At free water concentrations below 30 ppm, yellow/green colors are obtained. These colors progress through green to blue/green and finally blue/black at very high free water concentrations.
