3 overview

The pour point tester is used to measure the pour point of petroleum products. The pour point is the lowest temperature at which the preheated sample can flow after cooling under specified conditions. The cloud point meter is used to measure the cloud point of petroleum products. The cloud point is the sample at the bottom of the test tube after cooling under specified conditions The highest temperature at which wax crystals become cloudy. The pour point/cloud point analyzer adopts visual inspection or optical system monitoring for measurement. The main components of the pour point/cloud point tester include heating system, cooling system, optical test system (for automatic instruments) and test tube kits.

4 Measurement characteristics
