Roman Osborn: Works very well for the everyday hvac needs, I like that you can get all the different temperature air quality numbers in one device, super simple and easy to use.

Aftetshave57: Bon rapport qualité-prix. Pour vérifier le taux d'humidité des serres, des remises à machineries et des caves. Il peut aussi servir dans la maison. Il est cependant moins précis que les appareils professionnels tels que les FLUKE les REED mais si on a pas besoin d'une telle précision professionnelle, les lectures sont tout à fait acceptables. Il semble physiquement aussi solide que les appareils plud chers. La lecture n'est cependant pas instantanée et nécessite de prendre la mesure au moins 30 secondes avant d'être stable.

Shaun J.Shaun J.: This unit is very affordable and seems to be very sensitive. It doesn't come with instructions but it's super simple and easy to figure out. I was just surprised that it was as accurate and good quality for this price!
--Update-- I tested the thermometer function of this meter against a much more expensive Fluke thermocouple thermometer and found that it was within 1.5 degrees (2%). This is surprisingly accurate and probably as good as one could expect with different meters.

Dido who likes Fritos: I work on the side as a home painter. This is a must have. Gives accurate readings for relative air humidity and air temperature. Perfect before and after painting to determine humidity before and then set right ventilation/air flow for quick effective paint and primer drying. Makes job quicker. Also works great for area spot checks in large green house. Only reason did not give all 5 star review to accuracy is because I know there is more expensive higher calibrated "professional" equipment. This is a great value for quality purchase though.

Amazon Customer: Product was great, only thing is it needs a backlight, as the screen is dark.

AmazonianAmazonian: 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.

KyleKyle: 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...
