Portable Helium Spray Gun for Best Leak Detection Results

With our new intelligent add-on SMART-Spray, a portable, wire- and hoseless helium spray gun for the UL Family of leak detectors, you can elevate your leak detection to new heights:

Working with SMART-Spray makes your leak detection significantly faster, easier, more reliable and more effective while saving helium.

No connection hose, no effort, no errors: the new SMART-Spray makes leak testing more flexible and efficient than ever before. Forget time-consuming handling of large helium cylinders, working range limitation by a hose connection and time-consuming and error-prone manual adjustment of the helium flow.

SMART-Spray is fully compatible with the UL Family of leak detectors.

The new SMART-Spray for leak checking offers enhanced efficiency and flexibility. With this innovative helium spray gun, you can avoid the complexities of managing large helium cylinders, dealing with connection hoses, and manual adjustment of helium flow. SMART-Spray makes leak detection more streamlined, simplifies your testing processes, and saves helium by ensuring the lowest flow required to pinpoint your check spots.

Advantages at a glance

  • Hoseless handheld tool for maximum flexibility and easy handling
  • Precisely predefined helium quantity for optimum helium flow
  • Refillable mini cartridges (HeliCan) with more than 1,000 sprays
  • Integrated color display to indicate readiness for use and graphical or numerical leak rate indication
  • Status LEDs indicating helium spray duration and surpassing of leakrate threshold combinable with haptical vibration feedback
  • Simple control of the leak detector, such as via remote control
  • Integrated lighting for darker areas
  • USB-C charging port and replaceable battery

SMART-Spray can be operated with either 50 ml or 405 ml helium cartridges (HeliCan), depending on your preference for accessibility in narrow spaces or for extended use.


When filled to a maximum relative pressure of 6 bar, the 405 ml HeliCan provides over 5,000 sprays of 2 seconds at 12 sccm, while the 50 ml cartridge allows for more than 600 sprays of 2 seconds at 12 sccm. Using larger flows of 70, 250, or 1,100 sccm reduces endurance linearly, enabling integral testing.
