I'm currently using a digital thermometer from Target to measure the temp of my chems, but I tend to drop it in the water a lot, so I know know it's likely to die eventually. I'm looking on Freestyle for a thermometer, and I've narrowed it down to two. The first one is the Legacy Pro thermometer, which is 3.99USD http://www.freestylephoto.biz/62010-LegacyPro-6-inch-Glass-Thermometer The other is the Patterson, which is $25.99. http://www.freestylephoto.biz/62010-LegacyPro-6-inch-Glass-Thermometer Of the two, which is more accurate, or are they the same accuracy wise? If they are, the LEgacy PRo will be the one I get. The Patterson has the metal tip, which seems to me like it would adjust to changing temps faster since the liquid in the thermometer (Alcohol, I'm assuming) is in contact with the tip (or appears to me to be). The Legacy Pro looks from the picture like the thermometer is encased in a glass tube. Would that have any effect on accuracy? If it's not in direct contact with the water, wouldnt the reading be slightly off if the water temp is changing because the temperature of the air has to drop before there's a change in the reading of the thermometer? Am I just overanalyzing a trivial matter?
