HK-0248A Automatic Cold Filter Plugging Point Tester

Overview
HK-0248A Automatic Cold Filter Plugging Point Tester conforms to ASTM D6371 Standard Test Method for Cold Filter Plugging Point of Diesel and Heating Fuels. A specimen of the sample is cooled under specified conditions and, at intervals of 1℃, is drawn into a pipet under a controlled vacuum through a standardized wire mesh filter. The procedure is repeated, as the specimen continues to cool, for each 1℃ below the first test temperature. Testing is continued until the amount of wax crystals that have separated out of solution is sufficient to stop or slow down the flow so that the time taken to fill the pipet exceeds 60s or the fuel fails to return completely to the test jar before the fuel has cooled by a further 1℃.
The indicated temperature at which the last filtration was commenced is recorded as the CFPP
