EXPIRY : NOV-2025 COC *** 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. The Shell Water Detector is manufactured following strict quality assurance standards in a purpose-built, humidity-controlled facility. The manufacturer has ISO 9001:2008 accreditation for quality management, which covers manufacture, assembly, packaging and supply. The Shell Water Detector is proven and now comes in easier-to-use packaging, which is designed to enhance product quality assurance even further.
