Web26 mrt. 2016 · In a test specification based on GR-487, a humidity test is called out where we need to have a fixed specific humidity (i.e. 24 grams of water vapor per per kilogram of air). For a given specific humidity, the relative humidity will vary with temperature. WebFor example, you can check what is the dew point temperature at 90°F air temperature and 75% relative humidity. Use the slider and you should get this correct result: 81°F. On top of that, you can also consult the dew point temperature chart below (using this calculator, we can create the dew point calculator chart).
