Absolute Pressure decay: It exploits the “pressure decay” principle by pressurising the piece under test and detecting the pressure decay.
Differential pressure decay: the equipment detects the leakage by comparing the piece under test with a reference one which surely has no leakage.
Interception Compliance Measure: it allows to measure the leakages outside the piece under test, which will be introduced in a airtight bell.
Continuous leak measure: Ideal for household appliances and gas fields, it allows to make continuous leak tests. This is useful to analyse and repair the product under test (ex. Stove tops).
