I bought these because they were cheap and wanted to compare them to my other aquarium thermometers. Two sensors are placed on opposite ends of my 75 gallon tank and their readings are consistently within 0.1 degrees of each other. They also read the old-school mercury thermometers in the tank to the nearest degree. I will buy more.
