Dew Point Meter vs a Hygrometer Plus Arithmetic: Which Tells You the Truth?
A dew point meter measures a physical temperature directly, while a hygrometer plus arithmetic derives dew point from relative humidity and air temperature, so the two agree only when the inputs are accurate and the air is not changing.
