Mary,

Although they are more expensive than manometers, there is a ready supply of
fume hood monitors and alarms at http://www.safefumehood.com. There are
discounts for quantity.

Subject: [DCHAS-L] Air Flow Monitors for fume hoods

Does anyone have an inexpensive solution for adding an air flow monitor
to older fume hoods?  Is it now law that every fume hood (old and new)
have one?

Thanks
