One thing that needs to be explained is that when the room is quite dry and there is almost no humidity, its error will also become larger. Humidity is not like temperature, which can be accurate to plus or minus about 1 degree. Even in the laboratory, it cannot be done. This product is sufficient for home humidity measurement, and it must be much more accurate than the one on the humidifier! If you have special high requirements for humidity! Please tell me, there is a more accurate hygrometer, the price is about 200 yuan! This is only for home use, it will tell us whether the room needs humidification or dehumidification. As the guardian of your healthy room, it is quite competent!
