Normal level of humidity in the apartment where we spend a lot of time, is extremely important for good health. Unfortunately, in the conditions of modern apartments this indicator often does not meet standard (from 45 to 60%), especially in cold season when heating services works. Then there is question of measures for increase in humidity. And how it is possible to measure humidity level in the apartment? There are several available ways.
1. Buy in specialized shop the special device – hygrometer, the psychrometer or the household humidity indicator. Distinguish hygrometers hair, film, weight, electrolytic, ceramic and condensation. Each type has the features, but one base – hygrometric method of measurement or definition of dew point. The psychrometer is considered more precision instrument on measurement of humidity. Distinguish mechanical and electric psychrometers. Proceeding from indicators of this device, moist level is defined by means of special psychrometric tables or the psychrometric schedule. Today meteorological stations were available for sale so-called household (or house). They represent digital thermometers with indication of humidity. This universal device will show you both the air temperature, and humidity level, and the forthcoming changes in the nature. Visit specialized shop, ask for the help the consultant. He will help you to choose the device necessary for you.
2. Use one of air humidity level measuring methods in the apartment without special devices. Indications, of course, will be very approximate and conditional, nevertheless they will help to define humidity degree in your dwelling. Fill small glass with tap water. Put it in the fridge for 1.5-2 hours. Water has to cool down up to 3-4? C. Get glass and carry away it to that room where you want to learn humidity level. Establish glass with water in the center of the room (far away from the battery if you are engaged in measurements in winter time), its walls have to mist over. And further just observe. If in 5 minutes the glass remains misted over, so indoors the average level of humidity. If in 5 minutes of wall of glass have dried, so the humidity level lowered (i.e. air in the room too dry). If in 5 minutes on walls of the sweating glass streams, so humidity level high have begun to flow.
3. Observe window plants. They can ""report"" about the low level of humidity in the apartment. Especially broad-leaved. For example, monstera, dieffenbachia, asplenium, fatsia, pizoniya, ficus, etc. At low humidity the tips and edges of leaves at them dry up, become bumazhisty. Of course, if you regularly spray flowers from spray, they can not react to excessive houseplants, you increase humidity level in the apartment. Thus, flowers serve good service in apartments. Large number of living plants in the house in itself creates the increased air humidity so, varying their number, you can regulate this indicator in any given party.
4. Listen to the feelings. If you feel constant dryness and irritation in nose and in throat, so humidity level in your apartment is extremely low.
5. You can define relative humidity in the apartment, observing, the washed things which are hanged out in rooms how fast dry (if you owing to any reasons are forced to dry their houses). If linen dries quickly (literally within half an hour, and even it is less), so in your apartment air dry, and humidity low. And, on the contrary, if linen dries long, besides gets mouldy smell, so in the apartment very high humidity.
6. Build ""hygrometer"" the hands. Take fir cone. Place it on fanerka. Fix the center of cone by means of tack or adhesive tape. If scales quickly begin to reveal, so humidity in your apartment low if the cone long time is in "starting position", so humidity normal. Well, and if in a day its tips do not rise any up, so the level of humidity is high.
