SF6-filled detection systems for CHINT

SF6-filled detection systems for CHINT

For integral leak testing, the SF6 filled test piece is placed in a test chamber. The test chamber is then evacuated to an absolute pressure of about 10 – 20 mbar. SF6 escaping from the specimen and thus entering the test chamber is drawn into the system's detection chamber via the vacuum module.
