Dräger air flow indicators make air movement visible. The battery-powered Flow Check makes a harmless smoke cloud with the same density as air for ventilation, fume hood and leak checks; the Air Flow Tester uses smoke tubes and a rubber bulb for quick checks of air current direction and speed.
- Flow Check smoke has the same density as air, so it drifts with the slightest air movement
- Smoke comes from an environmentally safe alcohol-based fluid; works in any orientation, as single puffs or continuously
- One ampoule gives about 3 minutes of smoke; one battery charge runs about 20 minutes
- Flow Check kit: indicator, battery charger, 3 ampoules and battery pack in a transport case
- Air Flow Tester: tubes with fuming sulfuric acid make white smoke when air is pumped through with the bulb
- Air Flow Tester tubes reseal with rubber caps and stay usable until the smoke runs out
- For HVAC adjustment, fume hood and chimney checks, leak detection and air movement in mines and plants
