Preciva Digital Psychrometer Thermo-Hygrometer, LCD Mini Temperature and Humidity Meter with Dew Point and Wet Bulb Temperature Hygrometer for Industry, Agriculture, Meteorology (9V Battery Included)

Works great.

I’m a gadget geek and if I see a gadget I don’t have, I usually have to have it. So you guessed it, I saw this Preciva Digital Psychrometer Thermo-Hygrometer Temperature Meter and I had to have it. Even though I didn’t know exactly what this meter did at the time…. What I discovered is this Preciva meter is a temperature and humidity meter that features a wet-bulb and dry-bulb giving it the ability to gauge dew point temperature. I can definitely see many uses for this meter when these reading are important; I will mostly use it in my garage and house to monitor and adjust temperature and humidity. To use I just had to install the included 9-volt battery and the press the bottom “On” button to see the readings. You will find a larger numeric reading on top and a smaller numeric reading below. I will list the screens below: (I used 99.99 just as reference.) 1. 99.99 % RH / 99.99 C 2. 99.99 % RH / 99.99 F 3. 99.99 % RH / 99.99 C Dewpoint 4. 99.99 % RH / 99.99 F Dewpoint 5. 99.99 % RH / 99.99 C Wet Bulb 6. 99.99 % RH / 99.99 F Wet Bulb Essentially, there are 3 sets of readings: Relative Humidity followed by Temperature, Dew Point, and Wet Bulb in both in Celsius and Fahrenheit. Note: When powering on the meter it defaults to the last screen that was in use before being powered off. There is also a Max/Min button that is used to toggle between the current, minimum, and maximum readings for any of the combinations of reading listed above. The screen is clear and the primary readings are very readable even for my tired old eyes. However, I find that the smaller indicators ‘C’, ‘F’, ‘Dew Point’, and ‘Wet Bulb’ are hard to see and require me to put on reading glasses. There is also no backlight as indicated in the description. On the back of the meter is a 1/4” threaded receiver that lets you mount this to a tripod or camera mount, which comes in handy. As for accuracy, I have to take their word on that. I have many temperature and humidity gauges and the readings from this Preciva meter are consistent with them. In conclusion, so far I like this littler meter. The only slight negatives is some of the indicators being a little too small for me, and the lack of a backlight. I also wish the meter could sense temperature and humidity changes a little quicker, which would make it a little nice for finding and recording temperature and humidity fluctuations. I hope some of this information helped. If I experience any issues, I will update this review.

The Preciva Digital Psychrometer Thermo-Hygrometer is a handy tool for monitoring indoor conditions. Its LCD display provides readings for temperature, humidity, dew point, and wet bulb temperature - all essential data for optimizing your environment. I purchased this meter to assess the effectiveness of my humidifiers, and it performs admirably. The measurements seem accurate, allowing me to adjust my humidifiers accordingly. However, I did notice that holding the device causes the temperature and humidity readings to increase slightly. Nothing drastic, but worth keeping in mind. My only gripe is the brief duration of the backlight. It turns off rather quickly, making it tricky to read in low light situations. I wish it stayed illuminated longer for easier viewing. Aside from that minor quibble, this psychrometer fulfills its intended purpose well. It's compact, user-friendly, and includes a 9V battery. Whether you're tracking conditions for agriculture, industry, or personal comfort, this meter is a reliable choice. For the price, it's a solid investment. Just be aware of the short backlight time and slight fluctuations when handling the device. Otherwise, it's a useful gadget for staying on top of your environmental metrics.

Easy to use and accurate

Works but feel like it is a little off

Used this to verify when the weather was right for my home made snow making, small sized, and humidity reading seems good, haven't had to change the battery yet.

I love how fast this displays the temperature and humidity. Although it's best if you wait a couple of minutes for the humidity reading to stabilize. I used this to calibrate my thermostat reading as well as note the variation on my dehumidifier. Since all the equipment has a plus or minus range and different parts of a room may also vary do not expect all readings from your HVAC, dehumidifier and other meters to all be exactly the same all the time. That won't happen. Very pleased with this purchase.

It works as described. Decent value for money. One irritating miss is it has a curved bottom. Can't stand it up on a flat surface. Who would design something like that?

Muy buen producto por el precio

温度、湿度の他にもタイトル通り全て表示し、この精度だったのでコスパ最高です。 安い物や他の物だと精度が悪い物が多いので星5です。 個人で使う分には申し分ないかと思われます。

I'm always curious to know how humid my basement is, or how humid my sauna is. This hygrometer is battery powered, easy to replace the batteries, it works very well, a few different modes to calculate different types of humidity metrics.

素人が使うには使いにくい。。 表示モードがたくさん有り過ぎ！ 瞬間で早く計れるのかもしれないが、1,000円くらいの安いデジタルの奴で十分だと思った。

nada de calibrado no aconsejo
