Hey guys and gals. Got my Acu rite indoor/outdoor digital temperature and humidity with probe today. Got them set up in 3 of the 4 tanks. In my AFT's tank, I have the old dial temp and humidity ones too. I am leaving them in there to try and get an average, as well as for back up in case my batteries die. My question is this, Dial humidity says around 70%, digital says 54%. The temp dial says 70, digital temp says 75 and they are right next to each other... I am going to test it with a gun right now for temp but I am worried about the humidity... How do I know the digital one is right?
