Integrity Testers

Our latest model since introducing the first commercial automated integrity test instruments more than 25 years ago, the Integritest® 5 uses pressure decay measurements to determine filter integrity. Along with a system volume measurement, one pressure decay measurement is taken to determine the relevant flowrate for diffusion and HydroCorr™ tests. The Tangent Method is used to determine a filter bubble point from a series of pressure decays performed at increasing transmembrane pressures. Optimum pressures at which to take measurements are based on test parameters and ongoing readings, reducing the number of measurements needed to reliably map the filter’s profile and return an accurate result.
Key features include:

• Improved test algorithm for faster, simpler testing

• Intuitive software with help screens for every step

• Flexible displays, run information, and test collections to suit your process

• Networking functions such as multi-unit management and synchronization
