Scott k: I work for a commercial casework, architectural millwork Co. It is vital for us to record humidity readings on job sites as it effects our product greatly, these gauges give quick readings which we record daily.

Thosoc: I purchased this meter hoping to replace my worn-out Fluke meter on HVAC maintenance jobs. The package arrived quickly and was intact. The meter came with a black canvas bag for storage, a small screwdriver for installing the batteries, 4 off-brand AAA batteries, and a small 4-page user guide. Upon close inspection, here are my observations:
1) The device looks to be well-built with a heavy-padded exterior, and looks sort of similar to my worn-out Fluke meter, however, with a much shorter tip.
2) The readout is large with backlighting, and the buttons are large and responsive.
3) The user guide has illustrations and adequate instructions for battery installation, and how to use the buttons for different settings.
4) The temperature setting is always reset to Celsius scale upon powering up.
5) Ambiguous warranty period and services, since no information about the topics can be found in the user guide and/or on Amazon.

Once the batteries were installed, I turned it on and kept it nearby to the digital Trane HVAC control console in my house to check the measurements for accuracies, where I noticed the measured values of both temperature and humidity for any...

SHARON SHIRLEY: I have been searching and wasting money on other hygrometers so I was tickled to find this! It is very sturdy and well made. When you incubate peafowl chicks, you must have accurate readings! You can trust this one!

The sound of truth: Humidity was off at first but after contacting Protech ca, they sent me instructions on how to fix it. Works good now.

PDL: Fonctionne bien, lecture rapide, précis. Nous avons trouvé des pertes de chaleur à des endroits exiguës , et d'une grande précision. La lecture nous indique précisément l'endroit où nous avons une perte de chaleur (un endroit précis sur le mur est plus froid à l'intérieur). Très bien!

George C: 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...
