This gadget is just what I needed. In the winter with the heating on the humidity drops and I get nose bleeds. Now I can monitor just what is going on in each room and rectify the situation. This tool is so easily carried from room to room and has a really quick response with a reading.
This is the second one of this ETI model that I have bought. I was very happy with the first one, bought over 5 years ago, and bought the second one so that I could have readings from two different parts of the house. I am very pleased with the small size, and with the easy-to-read display.
I've been checking humidity against asthma symptoms with this gizmo for two weeks now.
It's measured accurately between 45 and 83% (it's not been dryer but I trust it will do lower as well)
It does take a little while to adjust its reading after moving from very humid to normal and vice versa, particularly if temperature also changes. If temperature remains constant the meter seems quicker to adjust.
I'm very happy with functionality.
Why only four stars? Because the shape and colour remind me of pregnancy and COVID tests. I would have much preferred a dark grey or black or even bright red if you want it easy to locate.
All in all happy with my purchase, let me know when you change the colour way and I'll buy a second one so I have one at home and with me where I go.
the specification, calibration and function, all as stated.
A useful home and office devivice.
I wanted a small, portable, non-permanent hygrometer to get a feel for humidity levels in various parts of my house, and this does the job very well! I like the fact I can switch it off when not in use (I don't know if this is the case for all monitors). Note, its battery is not a AAA but a CR2032 disc.
