TH-200 Digital Thermo-Hygrometer

description says:"Quick response and high accuracy. "it is neither. temp is at least 4 degrees too high, and when i put the unit in my freezer, set to -2f, three minutes later, the reading had dropped from 78f to 55f.

Much better than the UTi DTH10 digital hygrometer ordered then sent back. It was wildly off and had far fewer functions. This gives min. max. avg. for all modes and has only a +/- 3% error for Relative Humidity as compared to the UTi's (and most other's 5%.) It gives dew point, and a bunch of other reading that I don't really need but might some day. In use, when stationary with no wind from fans or AC the UTi fluctuated wildly, +/- up to 10 in RH mode. This Wagner unit is very steady. It had much better build quality and is thus hands down better that the UTi. Of course it isn't a Delmhorst or similar $300+ unit, but for $50 it is a much better value by far.

This little guy is still going strong. At a fraction of the cost of my YJ. I needed a backup and thought I'd try this one. Glad I did. Now, when I have a choice, I grab this one. And I use them every day. Go in, get wet bulb. Go out and check superheat. Adjust as needed. Thats my job and this helps me get it done.

I think the meter is reading high...not certai, maybe my other meter is off ...I'll be checking them this week.

Works easily and portable

Works great!!!
