- I have a chance to buy a rarely used Extech Thermo-Aneometer 451112 for a good price. I am wondering if this is a good tool to have and if this particular tool is of good quality.
I am also wondering if the new yellow mini Extech aneometers are as good as the 451112 or even better?
i personnaly don't like anemomters.
i would rather have a hood, but the cost is outa this world lol well outa my reach!!
i posted an extech thread a lil while back and got mixed answers from both sides of the fence.
told that the older meter s weren't that good.
extech owned by flir now, and newer meters are supposedly better.
i dunno, i'm still up in the air about extech. but if it's a good deal, and you know how to use an anemometer, go for it
If the price is good enough, I might try it out. A couple of my techs have purchased Extech stuff and have been satisfied for the price. Even with a hood, there are still times when you have to have a anemometer to traverse grilles and such that you can't get to with the hood.
I would be afraid to buy a use Extech I owned some
Extech and it does NOT take Wacke well.
If you know the history maybe if it is dirt cheap then give it a try.
If you help others then you are a Success
Take a look at the Testo 410-1 (velocity only) or the 410-2 velocity temperature and RH, WB/DB or the 417 and 416.
Anemometers have several advantages over other methods of measuring airflow including making a non density dependant measurement of airflow. They are handy also for proportional balancing of a system.
