Leak tester with a size control for the radiator core.
Biplatyna is a tool to test the air tightness of the radiator core and check the position of the connectors.
Biplatyny simultaneously checks the tightness of two cores by comparing the relative changes in internal pressure between them. Leak test takes place in the coolant circuit. Checking the position of the connectors takes place before the leak test, so that in case of a negative result, another test (leak test) does not take place.
