Hi Bob, Not that its an elaborate treatment, but...
"While the RFS-IIF may be operated in air, it achieves its best performance in vacuum which eliminates barometric sensitivity.All other environmental sensitivities (temperature, voltage, etc.) are negligible." above is from http://optoelectronics.perkinelmer.com/Catalog/Product.aspx?ProductID=RFS-IIF But chances that these surface at the surplus market are pretty slim... ;-( -- Björn >From the > Hi > > Yes indeed. > > There really isn't a lot of data out there on pressure on rubidiums.
