Leak testing can be carried out to ensure the suitability of the equipment for pressurized purging. The default pressure test setting is 2.5 psi.
Leak testing with the NEPS nitrogen purge system is a simple operation and has a sensitivity that is related to pressure degradation against time. The NEPS nitrogen purge system has a display resolution of 0.01 psi allowing users to achieve high sensitivities depending on the monitored time for the equipment under test to degrade from the initial test pressure.
The equipment volume must be considered when calculating the actual leak rate.
