Accuracy of Thermometers
Up until today I was using one of those Metal looking Hand on the Side of the Tank Thermometer. Mind you, this Temperature Gauge is probably 15 years old. ;-)
Today I bought your Typical Suction Cup Glass Tube Thermometer. It's made by Aqua Culture.
The old one reports 4 degrees higher than the new one. I tend to think the new one is the correct reading. But I don't really know, do I?
When in the store today I saw a new version that is Digital and sticks on the outside of the tank. Are those any good?
Any info on Thermometers would be helpful. Thanks!
