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. Fuel Test is authorized and approved by the Civil Aviation Administration of China. A 5 mL sample is sucked through the detector head into the syringe. An initial indication occurs at about 10 ppm when the capsule turns from a pale yellow to a pale green color. The color deepens to a dark green-blue, indicating a water content of 30 ppm.

CASRI水检测胶囊可用于指示操作温度下喷气燃料中游离水（悬浮水）的存在，该温度简单，快速且灵敏。 燃油测试是经中国民航总局授权和批准的。 通过检测头将5 mL样品吸入注射器。 当胶囊从浅黄色变成浅绿色时，初始指示出现在约10 ppm处。 颜色加深为深绿色-蓝色，表明水含量为30 ppm。
