What is Shell Water Detector?

The Shell Water Detector is a device for determining the presence in jet fuels of finely dispersed undissolved water in concentrations lower than those normally detectable by visual examination. Water dispersions of this type can result from the emulsification of a water/fuel mixture during pumping, or from the precipitation of dissolved water due to a fall in fuel temperature

How to use the Shell Water Detector?

Each time you should use a new capsule. The capsule should be fitted to the syringe, then the capsule and approximately half of the syringe is immersed in the sample under test and the plunger withdrawn until the fuel reaches the 5ml mark.
The capsule should be examined for any difference in colour between the inner wetted portion and the outer portion which is protected by the plastic moulding. It is important to note that:

  1. The screw cap should be replaced on the capsule container immediately after the required capsule has been removed to prevent discolouration of the remaining capsules by atmospheric humidity. Unused capsules should not be left lying about or kept loose in the pocket.
  2. A capsule should be used once only and then discarded because the sensitivity of the device is a function of the quantity of fuel passing through the paper
