For my tropical aquarium which has some of the fussier inhabitants, I wanted/needed a temperature reading that was absolutely scientific. Nominal accuracy certificate included. The $5, $10, and $20 thermometers were a waste of money. Now I hit the power button, put it in the tank, count to three and bingo. I'm getting readings to the nearest tenth of a degree. Guaranteed. Another switch converts Fahrenheit and Celsius. Expensive, but so does my fish, and worth the trust.
