Unfortunately, the display of the hygrometer and my dehumidifier significantly different opinion though I have both devices positioned so that the measurements are likely to be only slightly different. Nothing easier than that. You can calibrate the instrument. So followed the instructions and receive a humidity value of "120%". Thus, the display was adjusted to 100%. Then the unit is in normal operation showed massively too little. Meanwhile, the hygrometer at rel. Humidity 50% adapted to the display DERS air moistening. The displays differ in the range of 40% -70% rel. Humidity by 5% which is sufficiently accurate for me. The display values are currently at least plausible. Oh, the thermometer verhakelt be in the range of 20 ° C and can be moved with the parking Schaube no employees. I should return the equipment immediately. But after I proceeded in good faith according to the calibration instructions and the device has only shown crap I did not want to engage in discussions with the manufacturer / distributor me. As mentioned above, the display values are mitlerweile plausible, which is why I use it to control the air moistening. Again, I would not buy the device. If a "precision hygrometer" which is priced at the top of the equipment offered here after checking with the enclosed calibration instructions away from the target value indicates it has actually NULL earned stars.
