It is not advisable to test the thermometer by immersing it directly in cold water or hot water. Rapid heating or cooling can cause malfunctions in the internal electronic components. The fish tank thermometer should be placed in the fish tank and given some time to measure the correct temperature. The accuracy of the fish tank thermometer cannot reach the level of professional thermometers. In nature, the temperature of water changes significantly every day. Therefore, even if the temperature error in the fish tank reaches 3℉, it will not have any impact on the health of the fish.
