To further empower industrial production efficiency, JW Froehlich has launched a comprehensive range of leak test panels, each designed to address specific application scenarios and deliver exceptional performance.
The Series 200 Professional Panels
The Series 200 professional panels stand out for their versatility, serving both as stand-alone devices and integral parts of machinery. Particularly suited for sophisticated test applications, these panels feature comprehensive measurement result analysis and modern data communication, all based on a user-friendly Windows operating system. Their touchscreen interface and clear menu structure ensure intuitive navigation, providing real-time overviews of the measuring process through graphical result displays.

The Series 300 Leak Test Panels
For integration into machine lines and production facilities, the Series 300 leak test panels emerge as the ideal choice. Utilizing the decentralized master/slave principle and advanced satellite technology, these panels ensure reliable background measurement processes, which can be visualized on a standard Windows 7-based PC or HMI. This design enhances operational efficiency and seamless integration into existing production workflows.

The Series 400 Multifunctional Panels
The Series 400 multifunctional panels from JW Froehlich are engineered to minimize test times, a critical advantage for high-volume production environments. Equipped with 1 to 8 channels, these systems can simultaneously measure multiple different testing spaces and display results in real time on a large touchscreen. Their compact, closed-unit design also makes them highly suitable for integration into various machinery, saving valuable production space.

The Series 500 Universal Panel (Uni 500)
As part of the JW Froehlich Series 500, the Uni 500 universal panel boasts a modern user interface and flexible application capabilities, functioning both as a stand-alone device and as part of a system in machine lines and manufacturing plants. Built on the same satellite technology and decentralized master/slave principle as other Series 500 products, its measurement processes can be easily visualized on a standard tablet or HMI, enhancing operational convenience.

Notably, the JW Froehlich Uni 500 stands out as an all-in-one leak tester, integrating all commonly used air leak testing methods to meet diverse testing requirements. ·
Absolute Pressure Method: Particularly suitable for leak testing of small-volume workpieces.
Differential Pressure Method: Equipped with a high-resolution differential pressure transmitter, ensuring precise pressure change testing.
Mass Flow Method: Offering the fastest and most accurate solution for leak testing of large-volume workpieces.
This all-in-one design allows users to select the most appropriate testing method for their specific needs, making it an ideal, uncompromising flexible solution for test stations. It is also well-suited for early R&D analysis to determine the optimal testing method; once confirmed, users can seamlessly switch to corresponding leak testers (MPS500, MPS550, MFL500) for on-line production line testing, creating a cohesive testing ecosystem from R&D to mass production.
