Questions about dew point
Thread Content
The dew point is determined based on the air temperature and relative humidity. How are the values in those tables obtained? Why use a list instead of giving a calculation formula?

It’s quite simple – there are calculation formulas involved, but the calculations are complex; it’s not possible to carry out these calculations step by step in practical applications. Therefore, lookup tables are used! Moreover, there is also a significant discrepancy between actual measurements and calculations; it becomes very difficult to obtain valid values at -90 degrees. Almost all of the numerical values listed below are estimated values. The materials and methods of measurement, as well as the arithmetic circuits, result in varying degrees of curvature for the measurement lines. You can compare the curves of several products to find out. The dew point probe is calibrated every 6 months, and the calibration data is calculated from that.
