The SM380VINT & SM480VINT come equippeed with the ability to help you with pressure testing. The SMANs have a didicated "test tightness" button which engages the manifold's pressure test mode. This feature allows you to carry out a timed, temperature compensated test which can be viewed directly on the manifold itself. This means that you're able to view highly accurate and cruicial pressure measurements-without any false positives on leaks-easier, faster and better.
