Extech 45118 Mini Waterproof Thermo Anemometer

I bought this to balance the A/C ducts in my home. I was quite surprised at how bad the system was designed with small rooms receiving high CFM's and large rooms with very little. This tool does a nice job in calculating the CFM based on the measured duct opening. It reads the airspeed then uses the duct dimensions to display CFM. As a bonus the thing does IR temperature readings as well but my primary application was CFM measurement and this it does well. Easy to use with big bright display that is backlighted at the touch of a button. Great tool at a decent price compared to others on the market. It came with a very nice case that also holds the instruction book.

This is the second one I bought. Great for field work.

This anemometer is so easy to use. Did have to read instructions to set units, but no problems. Reliable and tough with accurate wind readings. The temps seem to be a little slow when removing from the vehicle and reactive to wind readings, hence the 4 stars.

It’s a good tool to have in a pinch if you work in construction. Winds are the enemy when it comes to working outdoors

Love how I can meassure the wind before wingfoiling.

They say it floats and is water resistant, but after floating in an inch of water for maybe 2 minutes it no longer worked. The O-ring in the battery cover and whatever other intrusion measures it has just aren't enough. Water was visibly inside the unit and it took 2-3 days of laying in the sun for the moisture to come out. Luckily it worked again afterwards, but I'm certainly not pleased. As a sailor, what good is something that can't get a little wet?If you want to tell people your product is water resistant, it better d@#$ well be because you know they'll put it to the test and be sour if it fails.It's a decent unit otherwise, but I'm starting to think they're just overselling the "features." Might have to return this thing.

I bought this before moving into a house with forced air to be able to balance the system. It seemed to work fine for a little bit, but now the blades don’t spin until they’re hit with a stiff wind and squeal like they’re rubbing internally. Probably next to zero accuracy to the reading considering those two things. Looks like I’m outside of the return window though, so there goes that

Easy to use and works as intended. A little bit of a cheap feel why value was rated 1 star less
