Zederkoff Digital Round with temp. Factory set with a button for temp C or F. $19.95 with free shipping. Put it next to two of my "Caliber 4R" (which I love) and the reading was a perfect match. Every one has raised the prices on the "Caliber 4R" and went surfing for an alternative and found this one, " an industry leading accuracy of +/- 2% RH with no adjustment ever".
