Wind Tunnel Air Flow Tracer
for effective air flow visualisation using a wand

Designed to facilitate the observation of air movements in many types of flow situations, primarily in wind tunnels.

The unit is easily transported, is rapid and simple to set up and use, and produces a controllable, non hazardous smoke effect.

The smoke is produced by peristaltically pumping an innocuous, medicinal quality white oil to the tip of a probe, where a low voltage electrical coil heats it to produce a dense plume of smoke, at exactly the position where it is needed.

The special probe is shaped to minimise wake generation, ensuring that the smoke can be entrained into the airstream smoothly. A stable and clearly defined plume of smoke can be generated at air speeds up to 90m/sec (200mph).


  • Clearly defined smoke plume up to 90m/sec
  • Variable smoke output controls
  • Simple to operate
  • Rapid start-up (3 minutes from switch on)
  • Low oil consumption
  • Fluid level indicator
  • Hand-held probe supplied
  • Extension handles available for probe up to 1.8m
  • Replaceable vaporiser tips
