The application of temperature and humidity clock 3 in 1

Scientific research shows that people are living in relative humidity 40% 60% feel most comfortable in the environment, indoor humidity in winter usually is only 15%, if long-term living in this kind of room, will appear dry, irritated and respiratory system disease. In the dry environment, human respiratory resistance is reduced, easy to cause or aggravate respiratory disease. The dry air, the influenza virus and can cause infection of gram positive bacteria breeding speed, but also easy as the dust in the air diffusion, cause disease. Besides, there are terrible at low temperature environment. Human exposure in low temperature environment for a long time, the center temperature decreases, can appear a series of cold symptoms: breathing and heart rate, trembling, headaches, etc. The temperature lower than the body comfortable temperature under the low temperature environment of the human body core temperature below 35 ℃, the body is in a state of supercooling. When the core body temperature down to 30 ~ 33 ℃, muscle from trembling to rigidity, loss of heat production, death will happen. Therefore, winter use heaters family should pay special attention to the humidity and temperature of the bedroom, best equipped with a temperature and humidity meter. 3 in 1 temperature and humidity clock is a wall-mountable temperature and humidity meter. The temperature and humidity meter scene shows temperature, intuitive and convenient; Safe and reliable, long life, fast reading. Materials for aluminum shell, wall hung, surface diameter of 300 mm, the scope for - 20 - 50摄氏度 10 - 100% rh ( 1 - 12) 1, the precision of temperature. 5 c, humidity & plusmn; 6% rh。 Have it, even in the winter, dry and carefree.
