Integrity Analyzer

The PMI Integrity Analyzer provides fully automated testing of filter integrity. The integrity test detects very small amounts of flow through a sample before the bubble point is reached, allowing early identification of defects, pinholes, or structural weaknesses.

Integrity Analyzer

Overview

The PMI Integrity Analyzer provides fully automated testing of filter integrity. The integrity test detects very small amounts of flow through a sample before the bubble point is reached, allowing early identification of defects, pinholes, or structural weaknesses. This user-friendly system performs non-destructive testing and accommodates a wide variety of sample types. In addition to integrity testing, the system can also measure bubble point.

  • Allows testing of sample under tension, compression, or elevated temperature to simulate actual operating conditions
  • Determines gas permeability of nearly impermeable samples (microflow permeability)
  • Windows-based software handles all control, measurement, data collection, and report generation; manual control also possible
  • Real-time graphical test display depicts testing status and results throughout operation
  • Non-destructive testing
  • Length of test less than 30 minutes
  • Wide range of acceptable sample sizes and types
  • Transparent sample chamber for visual confirmation
  • Minimal maintenance required
