E-PDQ Compact Micro-Flow air leak test instrument: testing in pressure and vacuum conditions PFEIFFER VACUUM

Compact Micro-Flow air leak test instrument: testing in pressure and vacuum conditions The E-PDQ is designed for the quick production leak testing of small components and ensures that products meet their leak tightness requirements. Its compact design makes the E-PDQ perfectly suitable for system integration. It is available as EQ version for pressure applications and as MQ version for vacuum applications. Customer benefits Compact design – easy integration Integrated pressure (respectively vacuum) reservoir – simple test setup Cost-efficient – fast return on investment Solution example...

Customer benefits Compact design for small footprint Rack-mounted design for testing multiple cavities simultaneously with the same machine Version EQ for Micro-Flow pressure testing Version MQ for Micro-Flow testing under vacuum Automated test circuit with valves and sequence controller Digital and analog I/O interface via Ethernet or serial port Easy-to-read LED that indicates test stat
