The SG2 Sound Generator emits powerful ultrasonic sound waves which will penetrate small holes and cracks, following the path a gas or liquid would take to cause a leak. The escaping ultrasound is then received and measured by the VPE detector.

Use in conjunction with the VPE or VPE1000 detector to test refrigerator/freezer door gaskets, truck/auto/boat window seals, trunk gaskets, aircraft cabins and various other tanks/vessels and more.

The SG2 may be used in continuous or burst mode at 49 kHz up to 115 dB at 30 cm. This highly recommended accessory provides tones for trouble shooting pressure vessels and air tight applications.
