Ultrasonic transmitter for tightness testing
SDT 200 mW SDT International

This small portable ultrasonic transmitter is equipped with one directional ultrasonic transducer. It has a built in rechargeable battery. The transmitter generates two commutating ultrasonic frequencies. This produces a recognisable sound, which facilitates the detection of leaks, even in noisy environments.
Depending on the size of the object to be tested and the background noise, the user can select between two transmitting power positions.
