The hygrometer is unfortunately long since broken and shows stehts same unrealistic readings at (held about 2 years). I would not buy anymore. Is this about to planned obsolescence?
The same ordered hygrometer "305011 Digital Thermo-Hygrometer Comfort Control" function in any case yet.
This combination of thermometer and hygrometer I ordered 305011 Digital Thermo-Hygrometer Comfort Control with 2 TFA.
Therefore, I can go into the differences:
Cosy pointed to a few% more than the two "More specifically". It also responded more slowly to changes in humidity.
The temperature was measured the same (good and fast).
The bar display shows the value, unfortunately, only in 25% steps on.
The color coding is compliant.
My Cosy hanging in the bathroom (I have glued it with a suction cup, which was not included in the Badfließen. For this I had to curtail some of the sucker, because the hole at the back of the unit is a bit small and was probably designed for nails ).
I tried to stand, of course. It sits perfectly and gives the Hygromether footing.
As a battery 1.5V AAA included. Rechargeable 1.2V AAA Sanyo accepted the instrument.
I find that the proportions and dimensions. The precision is adequate for my needs. Now I know how long I have to ventilate to prevent mold and if I have to heat more. Therefore 4 stars.
