Wet bulb thermometer or HUMICAP?
I have been looking for alternatives to the wet bulb methodology for measuring vapour pressure/specific humidity. In my fieldwork I have come across with serious problems when trying to maintain a phsychrometer after Frankenberger in the field for a long period. The experimental field is a cork-oak savanna with hot and dry summers. During dry periods,h the sock that transmits water to the wet bulb thermometer dries out completely and is clogged by dust and insects.
An alternative measurement technique could be the HUMICAP
Here I compare the theoretical accuracy of both sensors regarding the calculation of vapour pressure. RH refers to the relative humidity given by HUMICAP and T refers to wet bulb temperature given by the psychrometer. This is a simulation of what would the error in calculating vapour pressure be, if we used HUMICAP or psychrometer and took their accuracy into account.
