Disclosed is an inspection system for a cable, pipe or wire transit having a plurality of transit elements in a sealed installation of cables, pipes or wires at a site. A portable inspection device has a controller and an RFID interface. The transit has an RFID chip with a first memory area which stores an identity of the transit, and a second memory area. The controller reads the identity of the transit via the RFID interface, records detailed operational integrity status data of the transit elements, obtains a status indication representing an assessed overall operational integrity status of the transit based on the recorded detailed operational integrity status data, transmits the obtained status indication via the RFID interface to the transit for storage in the second memory area of the RFID chip, and makes the recorded detailed operational integrity status data or the obtained status indication available to a maintenance server together with the read transit identity.
