WebTo evaluate relative humidity, wet bulb temperature, and dew point, HVAC technicians traditionally used a sling psychrometer and psychrometric chart. Nowadays they use "humidity" meters that are accurate, more convenient, and usable in confined locations unsuitable for sling psychrometers. Temperature-humidity meters Web22 jul. 2024 · Relative humidity is determined by using the actual vapor pressure divided by the saturation vapor pressure (see below). Meteorologists also use dewpoint temperature as a measure of the amount of water vapor in the atmosphere. This is the temperature at which the atmosphere becomes saturated and dew starts to form.
