AccuFlux®
Designed to be efficient, accurate, and easy to use
Consistent with Meissner’s commitment to developing smart products that bolster quality, reduce risk and provide a second to none customer experience, the AccuFlux® Integrity Tester integrity test system is engineered to combine the highest levels of instrument accuracy, robustness, and ease of use. In an era where importance of quality and accuracy often takes a back seat to reducing cost, the AccuFlux® Integrity Tester stays true to its purpose of sacrificing nothing, providing assurance that each test performed is being done so in a way that only a company with over 30 years of filtration expertise can provide.
AccuFlux® Filter Integrity Tester Benefits Demo
The AccuFlux® Filter Integrity Tester is a testament to Meissner’s commitment to vertical integration. Key among the design of this system is a 15″ color, multi-touch user interface, which serves as a window into the intuitive and easy-to-use nature of the system. The AccuFlux® Integrity Tester features a recipe-driven test setup that allows a user to be performing tests within seconds of powering on the device. Once powered up, the user logs directly into the test screen, where a test recipe can be selected. After reviewing conveniently displayed test data, the user can start the test with the press of a button. While the test is being performed, all test settings and data are being stored to up to three (3) locations. Upon completion of a test, the user must acknowledge the result, at which point a test report is generated and saved to a .PDF file. These files as well as the test data also can be viewed from the system’s History screen. Setup of recipes is made simple by providing data for all supported Meissner filters. The system is compatible with filters from other manufacturers, although this data must be entered manually. Test data entry and recipe setup is limited to users of a specified permission level. A portion of what makes the system CFR 21, Part 11 compliant is its multi-tiered user administration system, which requires all users to have a unique, individual username and password. The user experience and usability of the system is enhanced with various features listed below:
Preinstalled filter data for Meissner filters
Built-in self-checks and tests, such as internal/external leak test and source pressure check
Built-in sensor calibration utility
Auto-generated detailed PDF test certificate
Editable test data for adding
non-Meissner filter
Multiple save locations, including network locations and USB devices
Recipe storage system for storing filter data, system data, and test setups
Tiered user system, including unique user login accounts

AccuFlux® Filter Integrity Tester – What’s Under the Hood
When designing the AccuFlux® Filter Integrity Tester, quality and performance were the No. 1 priority. The result is a system composed of up to three (3) highly accurate mass flow meters, providing the greatest level of accuracy at all points throughout the standard 0-250 mL/min flow range. The high level of flow control built into the system allows the diffusive flow tests to be performed in less than 3 minutes without sacrificing accuracy, and on systems containing as many as three 40″ filter elements. Bubble point tests are performed using a highly accurate pressure sensor and Meissner’s TransVector™ algorithm, completing bubble points tests in as little as 90 seconds.
AccuFlux® Integrity Tester employs a Quad core, Windows 10 industrial PC with integrated 15″ full-color, multi-touch screen. The use of a powerful PC is a must when running today’s anti-virus software and also yields great benefits when it comes to integrating the system with a network, using standard Windows-based accessories or applications and connecting the system to other network devices and printers. Some of the features that allow the AccuFlux® Integrity Tester to perform at such a high level are:
Windows 10 Full Function Industrial PC
