Item # 7900, Jorc Locator (Ultrasonic Air Leak Detector)

What produces ultrasound in a leak? When a gas passes through a restricted orifice under pressure, it is going from a pressurized laminar flow to low pressure turbulent flow. The turbulence generates a broad spectrum of sound. There are ultrasonic components in the sound and since the ultrasound will be the loudest by the leak site, the detection of these signals is usually quite simpe.

Commercial Benefits

• Ultrasonic leak detection to save money
• SMT/solid state hybrid heterodyne receiver
• Supplied in case, complete with headset and rubber focussing probes
• Production does not need to be disturbed when the LOCATOR is being used
• Fully automatic - no maintenance

Technical Advantages

• Leaks will be detected from a distance (up to 33 feet)
• Highly effective in locating leaks and incredibly simple to apply
• Very little time is required to locate leaks throughout a factory
