A high voltage loaded sharp end is applied next to an earth connected base and in between lays the plastic part we test. Should a hole exist in the part, ions will start moving from the earth to the sharp end. This will result in a loss of power and be translated into a leak.
While this method does not quantify the leak rate in terms of cc/min for example, it is the fastest ever invented to detect a leak in a go / no go process.
We have achieved cycle times of less than 7/10 of a second.
Leak Ranges: Depends on the size of the hole and the material of the part
Accuracy: Depends on the size of the hole and the material of the part
