The Integrity Tester provides fully automated analysis of filter integrity. The integrity test detects small amounts of flow through the sample before the bubble point is reached.

 The Integrity Tester provides fully automated analysis of filter integrity. The integrity test detects small amounts of flow through the sample before the bubble point is reached. The user-friendly Integrity Analyzer features non-destructive testing and can test a wide variety of samples. The integrity test can also measure bubble point.
 
Operation Principle
 A fully wetted sample is placed in the sample chamber and the chamber is sealed. Gas is then allowed to flow into the chamber behind the sample with increasing pressure. A flow meter is located in front of the sample and is used to detect gas flow through the sample prior to any pore being emptied of liquid, thus, the integrity is determined. When the pressure reaches a point that can overcome the capillary action of the liquid within the largest pore, the bubble point has been found. After determination of the bubble point, the pressure is increased and the flow is measured until all pores are empty.
 
Application
 Industries worldwide use the Integrity Analyzer for R&D and quality control. Samples often tested include filter media, membranes, paper and battery separators.
