The Air flow enters on one side of the test with the pressure sensing transducer monitoring on the other side.

The two air passages will not interact with one another during the test cycle.

The test head can be removed for cleaning – a quick rinse in water removes any crust from the test head.

The test head is designed to seal to the carboy spout in two ways – one is the downward pressure exerted by the air cylinder and the other is by the internal pressure of the car boy as the pressure increases.
