Direct measurement. No reference part, no approximations. The absolute decay method pressurizes the component under test and quantifies the actual pressure decay over a defined time window — delivering a linear, repeatable leak reading in mbar·l/s, cc/min, or Pa·m³/s.

An absolute decay leak tester is the right choice for single-cavity components — enclosures, housings, hydraulic circuits, heat exchangers, EV battery modules, medical devices — where medium to large volumes make the part response predictable and measurable. Widely used in automotive, HVAC, hydraulics, appliances, and medical device production.

ForTest absolute decay leak testers combine metrological precision, measurement stability, and native connectivity with production lines and MES systems. All models support full data traceability and periodic calibration → What is a Leak Test? Definition, Equipment & Rates
