I've got a 10 gallon tank with a ESU Thermostat, a Zoo-Med digital thermometer and a generic UTH. Additionally I have a Mini PE TempGun. My issue is that the digital thermometer and my thermostat are reading 87 or so, but when I check with my TempGun I get 100 or so. I am afraid to set the thermostat to 92 unless I'm 100% sure its reading accurately. The thermostat doesn't have a temp readout, but based on the starting and stopping of power to the UTH, it seem to be closer to the digital thermometer that the TempGun, but I keep reading that the TempGuns are more accurate... Which do I trust?
