Query: NOT any good in a greenhouse application!

I bought this thermometer to use in our Solar Gem greenhouse. However, aboveabout 80 degrees it's not even close to being accurate! Up to 80, it's just fine,and the outdoor sensor seems fine (below 80 - it's not that hot here now, so whoknows what it'll do then). When the interior of the greenhouse is 85-90F (as verified by 2 otherthermometers, both of which agree), this unit registers 107!! I won't bother sendingit back, as it's still useful for humidity and outdoor temps, as well as the timeI guess... but I had to add a different thermometer for getting an accurate readinginside the greenhouse. A $3 bargain kitchen dial thermometer from the grocery storeis VASTLY more accurate for my purpose.I wouldn't buy it again had I known it's so wacked out above 80F.
