The PAT-Cell-Press is the ideal, leakproof cell for pressure testing.

Our pressure test cell for the PAT series

The PAT-Cell-Press is the newest member of our PAT series. It is a pressure test cell for measuring gas evolution and drawing gas samples (option). Its advanced design includes a laser welded pressure sensor and glass-to-metal seals. The number of non-permanent seals is reduced to its minimum: a single PE seal between cell lid and base and a ferrule when the cell is ordered with the optional gas sample port.

In order to ensure best testing results, every PAT-Cell-Press is intensively tested for helium leaks. It is used with the PAT-Stand-1 docking station or in multi-channel configuration in the PAT-Chamber-16.

PAT-Press package

The PAT-Press is a complete single cell package for recording the pressure rise during battery formation and cycling, and for drawing gas samples from the headspace of the test cell. For testing with multiple PAT-Cell-Press test cells we recommend using the PAT-Chamber-16 or PAT-Tester-i-16.
