Draeger CH25301 Air Current Smoke Tube, Break-Off Tip, Glass
Draeger smoke tubes have been very popular in the HVAC and mining industries for many years. The reagent inside the smoke tube produces a visible aerosol plume when in contact with atmospheric humidity. A simple squeeze bulb pushes air through the tube to propel the smoke into the ambient air. Even the most gentle air currents are made visible.
