    Humidity/Temp Meter

    My Extech I loved just died after 5 years. Had an "Easy View" version. Have to replace it and was ready to buy the same one but want some input from anyone else. Don't have to have dual purpose, I really just need a good digital humidity meter. Have a TSI version but the thing burns up batteries daily and extech was maybe 1-2 times month. I work in mid-Florida area so we are a swamp and the thing gets a workout. Thanks for the input.

    The testo 605-H2 is the meter of choice, or the 610. They are both very easy to use and very accurate, and both have very long battery life. Normally over 1 year with moderate use.

    Check trutechtools.com under the humidity catagory.

    Testo makes the best RH sensor available.
    JLB,

    I also recommend the 605-H2, very good instrument, buy two if you can afford it!

    There are also a few other instruments that work very good depending on what you are measuring, but the H2 is great for ductwork.



    Jim, can you enlighten us on why Testo has the best rh instrument?

    WB / DB / rel hum / Delta H or T. I got very acclimated to the tool and could cut a 1/2" hole in ducting to measure everything at once. The similar tools I've seen have a fixed sensor on the display, the extech has a 4-5 ft cord for the sensor. I want the best so the testo seems to be the choice. The input is appreciated.

    For duct work the h2 is excellent! Buy 2!

    If measuring airflow from registers the 410-2 is a great tool as it does db,wb,rh, windchill, and has the benefit of a vane.

    The real pros use the Fluke 971

    I don't understand why you amatures use inferior tools.

    I use the Fluke 971 on cooling towers to residentials apps -- when are you rookies gonna learn?

    Inferior tools, I dont think so,

    The fluke 971 is a decent instrument, but is not the greatest thing out there.

    Good luck taking acurate measurements in ductwork!

    1st of all -- ARI recommends that you take wb & db before the evap coil; then, you take the db at the first outlet to allow for mixing.

    When you amatures get to my level, you might be able to complain.

    But, until you understand ARI concepts -- stfu.

    Lol, yeah you have no idea who or what you are talking about, and the fact that you are not even a pro member is even more classical!

    He would have to come out from under that rock and stop being so pompous.

    I have a feeling he might make the news soon.

    He's really on the ledge.

    His knowledge is like money to greedy people.

    Not going to do ya any good keeping it all to your self when your gone.

    I have a 971. Mediocre at best, temp off by 1.5 degree RH worse. Up for sale, you pay shipping! I have had the best luck with Testo and I will not spend my money on Fluke except for VOM's... at least until Testo starts making VOM's.

    P.S. It doesn't matter were you take your readings if the instrument is inaccurate.
