This instrument is the essential reference for periodic verifications. Its operating principle is simple and effective: It is mounted in parallel on your test circuit. It introduces a precise, controlled (and accurately known) artificial leak into the system. This allows you to verify that the measurement device can indicate the exact value of the simulated leak, thus confirming its calibration and proper functioning. The reference leak is not a standard component;

It is considered a precision instrument. It is custom-made according to the specific criteria of the part to be tested (pressure range, volume, and required leak rate). Each reference leak comes with its own calibration certificate, ensuring measurement traceability and compliance with quality standards.
