The drama continues- I bought a EXO-Terra Combo Digital Therm/Hum Meter w/Probe, to test it I placed it in the tank with my already exsisting Digital Thermometer and an Analog Thermometer, so I have 3 Thermometers in one tank going on, (2 Dig and 1 Analog), they all read something different and the 2 digital ones have a10 degree difference in Tempurture, how do you know which one to believe?
