Selina

Selinos jutiklio tolerancijos diapazonas yra +/- 3%. Norint palyginti higrometrų drėgmės rodmenis, matavimai turi būti atliekami tomis pačiomis sąlygomis (pvz., ta pati temperatūra) ir toje pačioje padėtyje. Vieno metro atstumas tarp dviejų higrometrų tam tikromis aplinkybėmis gali sukelti nukrypimą. Atkreipkite dėmesį, kad visi higrometrai turi tolerancijos diapazoną, paprastai +/- 5%. Nestatykite Selinos ant ar šalia radiatoriaus arba prie pat lango.

Basically, a hygrometer should be placed where the air humidity is to be measured. In order to make sure that Roger indicates the correct level of air humidity, the following should be taken into account when deciding where to place him: Air should be able to circulate freely. In other words, a hygrometer should not be placed on the floor in a corner or on a shelf behind books. Neither should a hygrometer be placed anywhere where there is a risk of air coming in from outside such as right next to windows or doors, for example. You should also choose a spot where the device is away from direct sunlight as otherwise the air humidity value may be distorted.
