VES’ experienced Sales Manager, Alex Garner will be attending Europe’s leading Hydrogen and Fuel Cells Exhibition in Hannover, Germany on Thursday 25th April.

Whether you’re an exhibitor or attending the show, please reach out and connect with Alex ( to discuss how our OptVol leak detection system offers a robust, reliable and cost-effective repeatable fuel cell plate testing solution.

OptVol is an all-in-one leak testing machine specifically designed for fuel cell manufacturers. Our helium leak testing machines that use our exclusive OptVol technology benefit from a small footprint, easily interchangeable tooling for different product variants, and a lightweight design. This enables ease of movement between production lines as production demands change.

Our all-in-one OptVol is built for leak testing the cooling, hydrogen, and oxygen circuit, detecting very low leak rates up to 1e10-5 mbar.l/sec (10% helium) and designed for production leak testing bipolar plates, fuel cell plates and fuel cells.

For assistance with our advanced leak testing solutions and customised systems, please contact our sales engineers by email at, or visit for more information.
