I would be grateful for advice (and there may  be a better newsgroup
to ask). I am looking to buy a humidity sensor for a gas exchange system. 
How successfully have vaisala-type sensors been used, is there 
anything around yet that holds its calibration better? Is it still best to 
go for a dew-point mirror sensor, and if so from where?
