I am working on the controller for a product that incorporates a humidity controlled chamber, such chamber is (generally) kept at rh80-95% but, even in normal usage, it is possible and acceptable that the humidity reaches 100% and condensing.
Honeywell HIH sensors, http://sensing.honeywell.com/index.php?ci_id=147072 , look great for the task, however they make a dinstinction between sensor that are suited for up to rh100% and those who are suited for rh100% and condensing.
Seems that the only difference between the two versions is the presence of a little "net" in front of the sensor orifice. Can I just use (for economical reasons outside the purpose of this question) the "non-condensing" version and protect it with a fine mesh in front of the orifice or the under-the-hood difference between the two is bigger that the physical protection of the sensor??
