Don - A little research gave me Cooper Atkins as the distributor of the pictured Digital Pocket Psychrometer SRH122, but that item was discontinued about a year ago. They may have others that truly are expensive, though I don't think that one was. The most substantial one I've come across is the Fluke 971 Digital Temperature Humidity meter. http://us.fluke.com/usen/Home/Search.asp?txtSearchBox=971&x=11&y=9 The problem with this one is that it's more expensive ($180 to $240) and it's not user calibratable. The problem with all of these devises is that, coming from China, they are not easily repaired. The one I mentioned is: http://www.generaltools.com/Products/Calibratable-Digital-Psychrometer__EP8706.aspx It's available from: http://www.techinstrument.com/acatalog/Pocket_Hygrometers.html The link that Don Rose provided you with is the Cooper Atkins unit that is no longer available. Tech instrument (above) has similar items. (SAMJR995) though it specs @ +/- 5%, not 1%, which would be very expensive, indeed. The gentleman I spoke with - Bob Berkhart - seemed knowledgeable and helpful. Always can find something that needs research.
