I recently purchased a cheap probe thermometer from Walmart and set up the probe under my warm hide. I kept my old Zilla thermo/hyrdometer on the warm side just to compare. The two consistently differ in temp readings by 5-10 degrees and in humidity readings by 10-20%. How can I be sure which one is accurate? (PS: The readings on the thermometer below are incorrect, pay them no mind.)




I set up my 20 gallon tank based heavily on the guidance offered here on the forum. I still need a thermostat for my UTH, which is currently off, and want to get either a ceramic heat emitter or RHP. Any other suggestions?
