Title: Very accurate thermometer but be careful of getting it wet
Review: I have a Sun Zip-O-Gage thermometer and am very impressed with its accuracy. On a recent cold day I compared it side-by-side to a Control Corporation Flip-Stick thermometer traceable to the National Institute of Standards and Technology and accurate to +/- 0.3 degrees Centigrade (ie. about a half degree Fahrenheit). The results in Fahrenheit are as follows:Flip-Stick: -0.3 degrees FZip-O-Gage: 0 degrees F (actually, half a hair below it)The Flip-Stick cost about $60. The Zip-O-Gage cost under $10.On the down side, however, the back of the Zip-O-Gage is not sealed. As a result, some liquid cleaner I was using to clean dirt off the unit leaked inside and stained the front of the temperature card. It doesn't affect the thermometer's operation or readability, but it does mar its appearance. So, be careful of getting the Zip-O-Gage wet. I wouldn't leave it exposed to the rain. Otherwise, a great little thermometer!
