Ultrasonic transmitters generate dual high frequency signals. These signals are small and therefore able to pass through very small leaks. When the transmitter is placed inside a volume (cargo hold for instance) the entire volume is flooded with dual ultrasonic waves. Use an SDT ultrasonic detector outside the volume to find and pinpoint the exact point of leakage.

The 200mW Bisonic Transmitter is used for checking tightness in smaller volumes or for spot checks after primary inspections. It is a single transmitter with bi-sonic (dual frequency) mode to eliminate standing waves. Ideal uses include spot checks on small vehicles, spot checks on building envelopes, clean rooms, refrigeration chambers, zero oxygen rooms, and smaller waterproof manholes and doors. For larger volumes (ships, cars, buses, airplanes, trains, etc…) use the SDT 8 Multi Transmitter.
