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.
