http://www.deltaohm.com/ver2010/uk/st_airQ.php?str=HD37AB1347 The brochure and the experts that Lewan and I have contacted say this instrument measures the enthalpy of steam. I expect they are right and the people who say otherwise here are wrong. I have no further comments on this issue. » This is wrong.The instrument measure RH and Temperature.Entalphy is CALCULATED by the measurement of RH and computed with a table.To compute properly the entalphy, you need a good RH measurement (and *engineer from delta ohm said that the probe cannot operate properly inside the reactor*).You need also a table that it’s consistent with the environment. The instrument is designed for IN-DOOR AIR QUALITY!I’ve had this discussion with Jed before, but surprising he again put this wrong claims.
