Drager Air Current Test Kit. Contains 10 smoke tubes, rubber caps, aspirator bulb, tube opener, instruction and carrying case.
Often the determination of airflow in HVAC ducts, fume hoods and other ventilation systems is necessary to locate problems. This Air Current Test Kit is a quick and inexpensive way to help make these determinations.
It works by creating a highly visible non-irritating dense white smoke that can be followed to determine the airflow direction.
To use, simply open the ends of the glass tubes with the supplied opener. Insert one end into the aspirator bulb. Squeeze the aspirator bulb to release a plume of smoke. Tubes are reusable until the medium has been extinguished. Caps are provided to cover the tube ends between uses.
*** Note: This Air Current Test Kit is non irritating and not suitable for respirator fit testing.
