A commercially available small humidity sensor with a very fast response was used in an unventilated diffusion porometer to measure leaf epidermal resistance. Measurements over calibrated dummy resistances showed that such a porometer had definite advantages in transpiration measurements in the field. In particular the waiting time before each measurement, necessary to obtain reproducible results with the commonly used LiCl sensor, could be shortened from 2 min to 15 s or even less.
