INTEGRITEST® 5 AUTOMATED TEST INSTRUMENT
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
EXACT-AIR™ II AUTOMATIC WATER-BASED TEST UNIT FOR HYDROPHOBIC FILTERS
Based on Remote Volume Technology, the Exact-Air™ II System is an automatic integrity test unit with an intermediate volume located between the filter to be tested and the testing device. Paired with the Integritest® 5 tester, it improves test accuracy and reproducibility under extremely critical temperature conditions.
By using the HydroCorr™ test method, a highly sensitive water-based integrity test for hydrophobic membrane filters, the Exact-Air™ II System offers users a unique opportunity to improve reliability, accuracy, reproducibility, and frequency of air filter testing, even under challenging operating conditions.
Key features include:
User-friendly software with touch screen display
Control of filling, testing, draining, and cleaning-in-place operations
Ease of validation
Bubble point and diffusion testing on hydrophilic filters
