The SONAPHONE T mobile ultrasonic transmitter is designed for the rapid and reliable detection of seal failures in windows, doors, cabins, vehicles and containers with sealing surfaces or rubber profile seals. In addition to applications in road and rail vehicle construction, the SONAPHONE T is also used in the ship and boat building industry and for testing fire safety doors, climatic chambers and clean rooms. Used in conjunction with an ultrasonic receiver from the SONAPHONE series, the SONAPHONE T enables efficient leak testing at a minimal cost. Due to the simple operating principle, the use of the device does not require a great deal of costly staff training and therefore minimises post-purchase costs.

The option of using the additional omnidirectional spherical transmitter SONOSPHERE enables the testing of both very large and awkwardly-shaped areas.
