Calculate RH of moist air at higher temp ranges accurately?

    Calculate RH of moist air at higher temp ranges accurately???

    Hey there :)
    Im using the Magnus relation for calculating the RH of air (sat pressure the RH) only to find it works good only for temperature ranges upto 100°C (with corrections to original Magnus relation!)
    Does anybody know a better method to calculate RH accurately (or thru Psychrometric charts-all charts I found have ranges upto 55°C only)??
    Any help is welcome!
    Thnx in advance :biggrin:

    wet bulb thermometer, dry thermometer and chart. Only way for the average engineer to do it.
