CASRI Water Detector (CWD)
The Casri Water Detection Capsules can be used to indicate the presence of free water (suspended water) in jet fuels at handling temperature, which is simple, rapid and sensitive. Casri is authorised and approved by the Civil Aviation Administration of China. A 5ml sample is drawn through the detector head into the syringe. An initial indication occurs at about 10ppm when the capsule turns from a pale yellow to a pale green colour. The colour deepens to a dark green-blue, indicating a water content of 30ppm.
