Anemometer?

[David Meiland]

Does anyone use or can anyone recommend a simple anemometer for measuring airflow from bath fans, range hoods, etc.? I'm looking for a way to approximate how well a vent fan works installed with its ductwork.

Go to the Home page, go to the far right side of the navigation bar, hit "Online Store"........

That takes you to one of our sponsors, Home Inspector Essentials. Anemometer is at the top of the selection list.

I've bought from them a few times recently. What I am looking for is some advice on which type/model will be most useful (and reasonably priced) for what I want to accomplish.

I used a cheap one ($150+-) for a few seasons, and honestly, I can tell just about as much with my hand and a piece of tissue paper.

Very unscientific, but useful, information from the hand and tissue. The hand was free, slight charge on the tissue.

So you're the one who taught Mike Holmes that trick[:-monkeyd

I watched my first Holmes episode (most of the it anyway) last night.

Why do all the guys on these TV construction shows lack necks, and have that pointy head shape?

The scientific concensus is that Neanderthals went extinct. If only scientists watched DIY TV...

What if you had to take a reasonably accurate airflow measurements and write it on a report? The BPI energy audit standard calls for measuring the performance of installed fans.

Well, in my 16 years of home inspecting I have never had the need to measure such a thing.

Now as an energy rater I could possibly see the use for one.

Right. Different gig.

Get a draft hood for measuring air flow, like the air flow technicians use. A simple anemometer measures MPH, not volume.

I use the fan flow meter from Energy Conservatory (looks like a dish pan with holes in it) and my DG700. Don't use it for home inspections, use it for my RESNET/BPI audits. Before that I used the hand/tissue method, did not know Holmes did it as well, glad I am smart like him.

[David Meiland]

Sometimes the answer is right in front of you. I already have a DG700, just need the dishpan. Thanks!
