Description
Overview
GAOTek portable digital hygrometer is designed for measuring carbon dioxide concentration, temperature, humidity, dew point temperature, and wet bulb temperature. Too much carbon dioxide indoors can easily lead to fatigue, a lack of concentration, and may contribute to sick building syndrome. A favorable indoor environment benefits overall health, improves immunity, and reduces the risk of diseases. The device is versatile and finds applications in various settings, including factories, workshops, greenhouses, clean rooms, industrial and agricultural facilities, as well as wine bars, hotels, hospitals, shopping markets, airports, railway stations, entertainment halls, and movie theaters
