For years, absolute pressure decay measurement has represented the cornerstone of ForTest. Born in clean rooms for biomedical and nuclear applications, it has evolved alongside industrial processes to become the most widespread method for leak testing. Simple and reliable. Twenty-four hours a day.

Absolute decay is chosen when a direct, linear reading is needed that is not very sensitive to part complexity: chambers, enclosures, hydraulic circuits, heat exchangers, automotive components, and single-use medical devices. It performs best on medium or large volumes, where the part response is predictable and thermal dynamics can be controlled.

ForTest equipment dedicated to absolute decay combines metrological precision, measurement stability, and operational continuity. They offer repeatable readings, advanced interfaces that simplify workflows, and native connectivity with production lines and MES systems. The wide range allows each model to be adapted to the process, while assistance and periodic calibrations ensure consistent quality and complete data traceability.
