Portable Dew Point Meter Range from -60 to +30 Deg C We are the indigenous manufacturer of portable dew point meter in India. The dew point (dew point temperature) is the temperature at which dew forms and is a measure of atmospheric moisture.The dew point is the saturation temperature for water in air. The dew point is associated with relative humidity. A high relative humidity implies that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and that the air is maximally saturated with water. When the moisture content remains constant and temperature increases, relative humidity decreases Hand-held portable design Dew Point Range : -80 to +30 Deg C Intrinsically safe IP67 rated Large 128 x 64 graphic display Internal data logger Lightweight hand-held sample system Convenient carrying bag to store hygrometer and all accessories
