cirrus flowpen

For the visualization of slight air movements, the medium used mustn't have its own engine. In the past, this was achieved by using chemicals that produced the finest particle or acid threads.

The new Cirrus FlowPen® works in contrast without acid or particles. Its electronically generated mist is condensed water vapor around an alcohol core and is therefore completely harmless.

By pressing the rubber ball, air is pressed through the cartridge, activating the fog generation. When the pressure is released, the fog generation stops and the cartridge can be stored until the next use, even for weeks or months.

The amount of fog is significantly less than the professional FlowMarker® or FlowPointer® systems, but sufficient to quickly and easily test for leaks in a furnace, window leaks or kitchen hood effectiveness.
