Static Leakrate Monitor

The SLM is a portable static leakrate monitor that may be used to measure leak rates on components and assemblies. Its lightweight & ergonomic design ensures ease of use in both a production & testing environment.  The SLM is equipped with a flow meter (25:1 turn-down ratio) and a test pressure sensor. The SLM quantifies a component’s leak rate by maintaining a constant gas pressure against the component being tested while measuring the gas flow rate needed to maintain the set test pressure. The SLM has an accuracy of 1% of full scale across its flow rate. Full scale flow ranges up to 20 slpm may be ordered.
