Draft Checker Airflow Detection Powder

Easily Test Fume Hood Safety

A quick, easy way to test the safety of fume hood exhaust before use. Just a squeeze or two from the plastic bottle dispenses a cloud of ultra-fine, lightweight silica powder, which remains suspended long enough to visually check whether or not the fume hood exhaust is functioning properly.

• Useful for detecting drafts, gas leaks, and air currents in rooms, ducts, and exhaust systems
• Amorphous silica powder is inert, non-toxic, and non-flammable
• 1.5 gm bottle
