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.  

regards
