Verifying a hood
    #22361576 - 10/11/15 01:45 AM (8 years, 3 months ago)

I'd like to test the efficiency of my hood but of course don't own an air sampler and can't determine ppm of anything.

I also don't own a smoke stick and I'm not so much worried about testing for laminar flow since math and my bic says I should have it.

I'm more concerned with testing for holes or how much gunk is getting through. Does anyone have any semi doable ideas to test the best I can with some petris and jars and what not?

Am I stuck sectioning the face of my hood into imaginary sectors and waving the face of a petri over the area, then labeling?
