Dräger Flow Check Ampoules Overview

Dräger Flow Check Ampoules, 3 ampoules and 1 nozzle (approximately 5 minutes of continuous smoke time per ampoule)
Dräger No. 6400812

The Dräger® Flow Check Airflow Indicator produces harmless smoke that has the same density as ambient air, making even slight air currents visible. Use Flow Check to identify leaks and to test the integrity of air-tight systems.


The battery-operated Dräger Flow Check Airflow Indicator electronically generates environmentally safe smoke for use during ventilation system testing. Carried by even the weakest airflow, Flow Check smoke indicates source, direction, and dispersion of air currents as well as relative air speed. The handheld Flow Check is ergonomically designed for easy one-hand operation. The instrument houses a replaceable ampoule that contains a special fluid mixture of alcohols. A small heating element at the head of the Flow Check heats the fluid, which condenses on contact with ambient air. The heating element temperature and quantity of ampoule fluid are electronically balanced. Flow Check is not suitable for respirator fit testing.
