The Leak Simulator from CTS partner company, innomatec is a flow meter that verifies a leak test instrument is correctly calibrated to a specified leak rate. When connected to a test instrument, the Leak Simulator measures and displays the flow rate at the external orifice port. It can also be used as an inline flow meter to verify instrument setup, with special adaptors. 

The Leak Simulator is easy to set up, provides inlet and outlet port threads and is powered by an internal AA battery.  This flow meter is an ideal tool for ensuring leak test systems are working accurately to specifications.
