Free slide rule for moisture measurement conversions
Michell Instruments has produced an absolute humidity and relative humidity slide rule. It provides the user with a fast, clear and simple slide rule formula - and is totally portable, unlike software packages. The useful tool also includes practical definitions and equations such as the equation for ppmv and the way of calculating a given saturation vapour pressure.
The front side of the slide rule calculates absolute humidity, allowing the user to align the measured dew point value with the operating pressure and then read the moisture content (ppmv) clearly and concisely. The user can then reverse the process to calculate dew point at pressure from ppmv.
The reverse side of the calculator allows the user to set the temperature (in degrees C or F) at a given relative humidity and then calculate the dew point. This process can then be reversed to calculate per cent relative humidity at a given temperature from the dew point.
