Digital Or Not

[elaine128]

how accurate are the digital thermometers, main reason i ask is ,i just bought a hydor ex heater and its set at 25 now my digital read is read out says 27.6 so i dug out 2 of my old thermometers and both of them register at 25, always thought these digital things were more accurate?

Standard glass thermometers are the most accurate at the end of the day, however digital thermometers are also pretty accurate and are easier to read. Remember that the temperature will also be influenced by the ambient room temperature and the heat given off equipment such as lighting.
