Abd, give me a link to what you're reading because on the webpage that Galantini provided a link to on NET website in his response to Krivits visit, here are the specs for humidity accuracy: +-2.5%RH (10...90% RH) +-3.5%RH remaining range And the usable temperature range is "-40C...+150C" and the usable RH range is "0...100% RH" Abd wrote: "But the meter has no capacity to measure that excess water, it would simply peg at 100%, it seems. I see no sign, anywhere, of any expert opinion that RH meters have any application to the measurement of steam quality." Yes, as I've been trying to explain all along, once you get to 100%RH, all remaining water will be in the form of liquid water because at the given temperature and pressure it is now saturated and can no longer support further water molecules as vapor. I've already answered your question as to HOW one can calculate that portion that is liquid water... Let's go thru this one step at a time (I'll start a new thread) and hopefully we'll learn something... -Mark
