I have inherited a couple of Wescor dew point microvolt meters, (HR - 33)
along with a couple of C - 51 sample chambers, some leaf psychrometers and
some soil psychrometers. I have some experience with the use of the later
Wescor osmometers where the chamber is integrated with the volt meter, but
I have little experience with the soil or leaf psychrometers. I would be
grateful for any advice on the use of the soil and leaf psychrometers,
particularly with regard to calibration and effects of variations in
temperature on measurements.
