Review: Easy to use - It's largely a matter of faith as to whether any hygrometer is giving accurate readings. There are ways of calibrating them, but these aren't all that reliable for a variety of reasons, like the fact that calibrating at one humidity level doesn't guarantee accuracy at other humidity levels. That's due to the fact that errors are nonlinear (not always off by a constant amount). Errors can be small (or even zero) over some portion of the range and large at others. Most home calibration methods, like the salt method, calibrate at the high extreme of the range, when our concern may be for accuracy elsewhere in the range. That issue is a tough one to get around, but digital sensors seem to have gotten better. In any case, taking any value of relative humidity as the gospel truth is a questionable proposition. What I look for is patterns of change in displayed RH as the environment changes and, to some degree, concurrence among multiple indicators. That's where this unit seems to excel. It gives me a reading that tracks (notice I didn't say "agrees") with other devices I have and with changes in the environment, such as running the heat like crazy and/or running a humidifier. Also, repeat measurements are reasonably stable under unchanging conditions. So, the readings are reliable (notice I didn't say "accurate"). The various bits of information the unit provides are convenient. For example, the dew point is sometimes more informative than the RH. This unit displays that. To sum up, even though I have no certainty that the readings this hygrometer gives me are precisely accurate RH values, I think it does about as well as you can expect in a consumer-grade product. It's consistent, easy to use, easy to read, compact, and affordable. If you need more than that, then you probably should be looking at laboratory equipment rather than something like this hygrometer. I like it and recommend it for most uses outside of a laboratory. It might even be fine in a lab but I'd need further validation tests to know that. In the real world, at affordable prices, in a convenient form factor, I think this is pretty much as good as it gets.
Review: It works very well and is super accurate! - This is only my first day with this product so hopefully nothing goes awry. But so far this instrument is absolutely amazing!! I already have hygrometers with room temp and relative humidity but I wanted more info. I wanted the dew point for a more accurate assessment of the indoor environment. And that's exactly whst I got! The room temp and RH match the other hygrometer readings within ~.5+/- degrees. Amazing! So I feel pretty confident with the accuracy of the readings. I am super happy with this product and would recommended it with confidence.

## Questions & Answers

**Q: The girl in the video says this will measure wind speed????**
A: I dont believe it does measure wind speed

**Q: Does this HT607 humidity meter show wet bulb temp in Fahrenheit or celsius only?**
A: Thank you for your question. HT607 psychrometer meter has 2 temperature units, ℉, and ℃, which can be adjusted according to your needs.

**Q: How accurate is this device?**
A: It’s accurate. Double checked with the temperature readings on the WeatherApp.

**Q: Does it use bateries or is rechargable?**
A: Thank you for your question. Our HT607 humidity meter and temperture use the bateries, the bateries need use 3*AAA.
