Protmex PT6508 Temperature Humidity Meter, Digital Thermometer Hygrometer Monitor with Ambient, Dew Point, Wet Bulb for Indoor/Outdoor MIN, MAX, Data Hold, LCD Backlight

Took a chance on this not well-known brand. I've been using this in my HVAC career. It is accurate and very easy to use. I can honestly say it's the best hygrometer I've tried yet. It has regular dry bulb and relative humidity readings.. It also has dew point and wet bulb temperature readings. And many other features also. For the he price, this one is a winner

Works good!

Great hygrometer. Good quality, use for work and think it will last for awhile, with proper care. Easy to use, and easy to read. Can't speak on battery life yet. I didn't have anything to calibrate and/or compare to, so don't know how "precise" it is either, but provided data within a range that "seemed" correct, even if off a percent or so.

Good price, good features, seems accurate. Fast response. Overall, very good value.

i used this tool to verify that i in fact would benefit from installing a very expensive Aprilaire 800 humidifier ( with the installation it was over 2 thousand dollars ) ... my worthelss Extech hygrometer ( the home model with big screen ) was telling me that all isn't so bad but my cracked skin was telling me otherwise ... this Protmex confirmed that my skin was telling me the truth and that humidity was abysmal - i went ahead with Aprilaire 800 installation and it was just game changing - no more sore throat, dry eyes, cracked skin etc ... one annoyance is it always starts in Celsius and you have to press the button to switch to F ... wish it remembered my preference. but it's overall well made, 10 times more accurate than Extech and 100 times faster. Extech ( the home model with big screen ) would take about half an hour to stabilize on a ( wrong ) reading when moved from room to room. This unit takes maybe 30 seconds to stabilize on a good reading. When moving from room to room the reading starts changing literally within a second or two of entering a different room ! ! ! It is SO sensitive ! For example if you walk into a bathroom after somebody took a shower there the numbers will start climbing the very moment you walk into that room ! And about 30 seconds later they will pretty much stabilize at a new reading unless the temperature is also different. It takes longer ( about 5 minutes ) when there is a difference in room temperature. all in all outstanding for home use. don't know if it's good enough for professional use.

Very happy with my Protmex 6508. Controls and readout are intuitive, making it very simple to use.

Works good

Does what it's supposed to do.
